vacuum lines and shaking like a seizure

[paratender2003]

this is how i feel for the last year! i need some help bad! i have a 1988 lebaron turbo 2.2 and need help w/the vacuum lines. also the car idles fine but shakes badly. engine rebuilt and the motor mounts are brand new. i need some pics of the an engine that has the lines in the correct way. the dealer does not even know how to fix them and all the shops wont touch the car. also there is a 3rd vacuum port on the top of the throtle body that the engine guy capped off. is this needed? is there supposed to be a vacuum sorce to the waste gate cause that just runs to the map sensor selenoid. i tried to use the diagram but can not figure it out. please help me. thank you!

I assume there is emissions in north carolina and your not aloud to remove any pollution control devices? (typical canuck question)

If you have any mechanical know how at all this shouldnt be to hard.
88 Lebaron Turbo. If it doesnt need to get safetied or inspected in the next while this is what you can do. What id do is rip all your lines out and put them in a pile on the floor. If its old brittle hose go grab some new stuff! If not you can just reuse the old stuff if its needed.

If you absoultely need the emissions stuff hooked up, you might be able to just make it look like its hooked up the day you take your car to be inspected and emissions tested.

Youll have to find where you want to run all the hoses from. Should be a spot on the intake you can start from. You should only need these lines.


Brake booster - Should run from the back of your intake (behind the throttle body) over to your brake booster.

Fuel Pressure Regulator - Should run from the vacumm source on the intake over to the FPR.

Map Sensor - Should run from the vacuum source on the intake over to the map sensor. Usually runs along side the FPR hose.

Boost controller - This depends on what your running.
If your running a manual boost controller, it goes from the vacuum source, to the MBC (g valve) to the wastegate actuator on the back of the turbo.

If your running the stock boost solenoid, the vac hose comes from the source on the intake, over to the boost solenoid on the passenger side fender, then from a different port on the boost solenoid (youll have to take a look at whice ones) over the motor then down to the wastegate actuator. (grey can on the back of the turbocharger... (I dont have this setup so if im wrong someone please correct me lol)


Both ports on top of the TB can be capped off.

Too be honest, I havent seen a 2.2 that didnt vibrate at idle, and some vibrate more than others. If it shakes really bad, it could be that you have a bent flexplate or flywheel or its even possible that since your vaccum lines arent right ( I am guessing here) the EGR valve isnt working right and its causing the really rough idle. As for the vaccum lines, I would just start from scratch and do them yourself. You should have a diagram under the hood (at least mine does) that you can follow and redo it all.

Thanks to whosever spectacular engine bay im drew all over! lol

[paratender2003]

ill try this in the am w/the vac lines. just 1 ? waramp. what is the mbc or g valve you stated? im not familiar with that. one other thing.......is there supposed to be 3 ports on the throttle body or only 2? and are they needed. sorry for sounding so stupid.

What do you mean by Just 1?

The MBC is a Manual Boost Controller. Around here they call it a G valve. Its a way of controlling the boost. Youll get into this if you ever start making this car fast. Alot of TD guys use the G valve.

Just ignore the G valve in the pic.
What youll need is a hose going from the source, to the boost solenoid, then to the wastegate actuator. They should all be labeled in the pic.

Again, i run a gvalve so if im wrong someone please correct me.

There are two ports on the top of it. I think there used in a stock situation, however both mine have been capped off for about 2 years. I dont think there necesary. Cap em.

[paratender2003]

thanks again. the pic really helped me out. have a good one and ill see how it goes in the am. the just 1 thing meant just one question. im used to using all types of easy spelling at work and i forget that im not there some times.

[Waramp]

Im bored so heres another.

Can someone else chime in and tell me if the setup for the Boost Solenoid is correct?
Did the factory use anything to bleed off the pressure in the hose that goes from the boost solenoid to the wastegate actuator? Or does the boost solenoid opening again bleed the pressure off?

[paratender2003]

my engine does not look like the pics that are listed. does this matter? i do not have an intercooler on my engine. im not sure if its a t2 or t1. i fix people for a living and just tinker w/the car. sorry...ignorant again

[Waramp]

Your engine is turbo though correct?
Turbo 1 and a Turbo II with the intercooler are not much different. The hoses will still all go to the same places. Just ignore all the piping in there.

Now, if its not turbo then there is alot of difference.

[paratender2003]

yes the car is a turbo. i have yet to do the vac lines and see if it works. i need to get some parts and caps and t's and such to get it done. thanks for the help.

[paratender2003]

can anyone send me a pic of the mbc valve is on a stock 88 2.2 turbo? thuere are 2 vac lines comming from the back of the turbo. one is the one from the waste gate and the other comes from the bottom of the turbo. is the bottom one the mbc valve or the top one?

Garrett T1's and T2 run the wastegate solenoid completely opposite of the T1 Mitsu cars. So all is not the same when it comes to stock vac lines. When running a MBC, go straight from an intake source to the barb on the actuator that's on the turbo and take the stock solenoid completely out of the circuit.

[paratender2003]

my car is stock and i dont have a mbc. the only ports i have are from the wastegate and then the bottom of the torbo. is the bottom on for the cruise controll and do i need vac to the waste gate and what about the bov line? im lost here guys and need some help.
