Almost Fixed, Few more problems
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?
