Almost Fixed, Few more problems

[americankozak2]

Hey all, its been a while since I have posted anything. The shadow (1989 2.2L TBI) has been progressing slowly since I am away from home and can only get to the car once every several months.

On my last trip home, I finally fixed the vent issue where if you went WOT the vents would only blow to the floor. It was a one way check valve off of the brake booster that fed vacuum to the dash that went bad.

My next problem to tackle is the car appears to only be firing on 3 cylinders when you first start the engine. Like, the RPMS sit at around 5-600 and the engine sounds like its misfiring. If i give the engine some gas/throttle and take it to 1500 rpm or a little more for like 5 seconds, then let go of the gas, it runs and purrs just like its suppose to on all four cylinders and I dont have any further issues whats so ever. It does not matter if it is a hot start or cold start situation. It has a complete ignition tuneup, so I know it is not a spark issue as a baseline to start off with. Looking to start accumulating ideas for the next time im hope to diagnose.

Also, for the life of me, i could not find where the preheat tube was suppose to attach off the exhaust manifold. Can someone please post a pic of where it attaches to the exhaust manifold for me that way I can pass it on to my brother who is still at home so he can get it on there?

Thanks all

The exhaust mani has a flimsy shied that the preheat tube should go on. If that shield is missing (which many are) then of course it has no place to go. If getting thru emissions testing, just fake them out by routing it back there and zip tie it to that 3/4" round metal tube. If they try to pull on it it wont move since its zip tied. Been there done that.

If you can get the car down to the Triangle, VA area (20 minutes south) I can help you trouble shoot some problems with it. I have a TBI car my son drives and I'm well versed in those type of problems, plus 25 years building the turbo dodges.

I am currently several states away and cannot make that trip with the car for that reason. I will take you up on that offer next time im back in the area if i havent figured out the problem beforehand.

If you have a n/a, could you shoot a picture of the shield your talking about (where the hose connects) because I do not remember seeing that shield when I was working down there last.

on the shield there will be a round empty connector on it sticking up, connect the pipe to that and the nipple on the bottom of the airbox

Alrighty, ive passed that info on to my brother to take a look.

Any ideas as far as the startup condition?

[Steve in Va]

Startup conditions are hard to diagnose over the net.

How old is the fuel pump?
How old is the cat converter?

My kids 91 Daytona ran like crap on startup. I noticed steam coming from the exhaust mani by the EGR valve. Put a new cat converter on it and the problem went away.

Take a overheard shot of the position of the distribuer and post it up here. You may be off a few teeth on timiing or something, just a quess.

1) i am not home anymore, i cant do anything/take pics/work on it/ ect..

2) it got a brand new exhaust system from the converter back 2 weeks ago and the problem didnt go away, i thought it was a blocked cat myself but that didnt solve it
