MrsArcade is keeping the peace

I have wanted a turbo minivan for a long time, but have never found one. My neighbor had a New Yorker Turbo. He passed away and I bought it from the estate. I knew the car had been sitting for quite a while and at least needed a starter. I swapped the starter, it took 3 starters to get a good one. First starter was lifetime replacement from advance auto, rebuilt in china...failed within 10 starts. Second starter was lifetime from autozone. It also failed within 10 starts...but there is a reason...I exchanged the autozone starter and the new one had booklets zip tied to it as well as a new stud bolt in a bag. The first autozone starter did not have these. I am pretty sure the first one was returned and unfortunately for me put back into stock. I would not walk out of autozone with a lifetime starter unless it has the books etc attached.

Next I had to deal with no brakes...pedal went to the floor. No leaks anywhere and fluid levels did not drop. I replaced master cylinder and after bleeding everything the brakes are great.

Now that it starts and stops, I need to get it running well.

The cel was lit and I was getting code 13. The baro solenoid is bad. it will not allow vacuum to reach the map sensor. The solenoid is not shorted or open, but it will not click or do anything when voltage is applied. I can order this solenoid and will.

I bypassed the baro and hooked vacuum straight to the map sensor and the car will idle and run, but not well. Cel does not light with map hooked to vac.

Testing vacuum at idle showed about 18...with the needle vibrating down to 17 or 16. Tested at line to baro solenoid.

Tested dual solenoid: The wastegate solenoid held vacuum at the wastegate port then dumped when voltage applied. Did not test if it gets voltage from plug yet. The other solenoid (egr) Acted similarly to the baro, it held vac at the canister port, would build a little pressure at the vacuum source port and the pressure would bleed off in a few seconds. The egr solenoid is not shorted or open, but it does nothing when voltage is applied. I plan to plug the vac source line until I can replace the egr solenoid so there is not a vac leak. Does anyone have a source for a compatible solenoid, either dual or just for the egr?

The car starts and can be driven, but it seems it can only go lower rpms. There is no tach, so I have no numbers. At wot the car doesn't accelerate at all. I have to press very lightly to accelerate. As the rpms increase, the car starts to stutter until it shifts and rpms drop, then it gets a little power again. This is with the vac source bypassing the baro and hooked directly to the map. Will the lack of baro readings and bad egr solenoid cause the car to run this poorly? Someone said it might be in limp in mode. The car will shift gears, I thought limp in mode locked trans in 2nd?

I have a vacuum pump/gauge and I want to test as many thing for leaks etc as I can, but I don't know the process(es). If you can tell me where to hook the pump and what the test procedure is, that would be great.

The clock has started, I put a 30 day tag on the New Yorker yesterday. I need to get it running well asap so I can sell our Escort and transfer the plates.

Also, I hooked a test light to the baro while the car was idling and it never lit. Should it light when you turn the car to run but not keep going to start? The +voltage is present, I guess the ecm is not closing ground. I am only getting error 13. If I unplug the baro I get error 37, but as long as it is plugged in there is no 37 error. I was wondering if it quits checking baro if it doesnt see a change etween vac and baro the first time it checks?

I plugged the vacuum line to the egr solenoid. I unhooked the negative terminal to clear the codes. just codes 12 and 55 now. The car is running better, but I am sure it is still low on power. It also backfires through the intake sometimes.

Have you pulled the valve cover to make sure all the rockers are on the valves as well? The backfire through the intake is what leads me to say check those.

Not having the Baro Solenoid connected to a vacuum source will not cause any driveability issues that you will notice unless you do constant driving to a different elevation without ever turning the car off.

As already stated be sure your valvetrain is intact and all valves are opening/closing.
All of your symptoms of loss of power, backfire thru the intake all sound like a Cam Timing issue.
Backfire thru the intake is almost always(99%)caused by valves not opening at the proper time or ignition happening at the wrong time.
The only condition that you have that disputes this is 18" HG which is normal...???

Verify all basics are correct and go from there.

BTW...Limp Mode(Failure)on your car would be related to a hard fault with the CEL illuminated, not the trans being in failure and stuck in 2nd gear.
Since you have no fault codes stored and the CEL is not illuminated you are not in "limp mode".
Also, as the vehicles got newer the controllers became smarter the CEL may be illuminated and you may not even notice any difference in driveability and would have no idea there was an issue if the CEL was not lit.
The "dumb" controllers were mostly used 84-87.

T.hanks for the great info. I am not sure how to tighten/loosen the timing belt. Also, until I get things sorted out, will the valve cover reseal well enough that I can wait to replace the gasket until I have it running right, or will it cause vacuum issues if I don't replace the gasket each time the valve cover is removed?

I am not sure how to insert a video, but I will try. Since the vacuum at idle is of interest, here is a clip:

that didn't work, just cut and paste the whole URL and we can look at the vid.


The Valve cover doesn't affect engine vacuum. But if you remove it you'll need to reseal it with new end seals and RTV. The 89+ valve covers have a reuseable 1 piece rubber gasket.

Since our cars use MAP vs. MAF there will not be any driveability issues due to a loose valve cover.
You will however have oil leaking.

Update: the car is running pretty well. I did nothing to it but drive it. It runs pretty well and is no longer backfiring through the intake. I have run it up to 70mph with no real issues...as long as I don't stomp on the gas. Moderate acceleration is good. Pedal to the floor is no good. The rpms go up but the car doesn't accelerate. Could this be overboost?

Nope...
Overboost shutdown will be a violent jerking as the controller kills fuel and ignition when boost limits are too high and then turns it back on when boost levels come back to normal.
This will continue as long as you stay in the throttle or until engine damage occurs.

Your issue is going to be related to a basic issue such as...
Cam/Ignition Timing
Fuel Pressure
Restriction in the Air Intake or Exhaust System

Another update...
I was driving tonight, cruise was set at 68. The car started losing power. It was back where only the very top of the gas pedal would do anything. After shutting the car off it would not restart. It acted like it was out of gas. I tried to start it a dozen times. I was thinking the fuel filter might be plugged up. I pulled the fuel line and it let out a large amount of "air". It hissed and "air" was coming from the fuel rail side. It took a couple of seconds for the pressure to finish releasing. I have never seen that before. I hooked the fuel line back up and pulled the vacuum line to the fuel pressure regulator. The car started. I hooked the vac line back up and drove home. Does this sound like the fuel pressure regulator is bad?

Thanks, I will get the autozone loaner set and hopefully get this figured out.

I pulled the fpr and the vac tube was pretty well plugged up. The vac line was gunked up too. It did not smell of fuel. I cleaned the vac gtube on the fpr as well as the vac line. I tested the fpr to see if it would hold vacuum and it did.

I put it all back together and the car is running even better. I still don't think I am getting any boost, or at least not much. Is there a way to test the wastegate? I plan to get the fuel pressure test as well as a timing light so I can verify timing is correct and will check cam timing too.

Thanks again for all the advice, help, and manual pages.
