Hey guys I am in need of some help. I have a 1996 Talon TSI FWD. I just bought this car about a month ago and makes it my #4 DSM. I really save this car from a young guy but anyways on to my problem.
I had no issues with this thing until a few days ago. It is not my DD and is more of a toy when I want to raise some hell for 20 or so minutes.
It idles rough and has no power when accelerating. It did have a rough idle until it warmed up and would drive fine. I took it out for a spin one evening and it was running fine, stopped at a buddies house shot the shit a bit and when I left I noticed it had the loss of power while accelerating. When I came to a stop it died and I got her home as quick as I could. It feels as if it has one cylinder misfire and exhaust note sounds as if I have one cylinder down.
I noticed the PO had removed the CTS and was running a mechanical Temp gauge. I installed a new CTS after the issue started and changed the plugs. The old plugs looked ok but I figured they need to go since it had no CTS and no telling how long it was like that. Still the car doesn't want to idle and sounds like a misfire. I turned the BISS out to raise the idle so I can do some checking while keeping it running. It has good spark from coils and from wires to plugs.( I just pulled the wires from coils and plugs while it was running). It does idle good at 1600 rpm with the BISS out and my Wideband shows 13.6-14.0 until randomly it goes way lean to 18 -19 and I seen as high as 22 but it almost dies as I feather the peddle and raise rpms to 3500 or so and slowly decel to allow it to idle again.( still feels like a misfire when i accelerate it though)
I then started looking for boost leaks. I dont have a BLT or a compressor so I used some brake cleaner and sprayed my IC piping and checked around the injectors, TB and everywhere. Produced no different results.
So I started pulling my injector wires while it was running and #2 and #3 idle or accelerating have no difference when off. I pull #1 or #4 and I know for sure they work cause the engine shakes and tries to die so I quickly plug them back in.
These are the stock 450cc injectors. I am thinking either fuel supply is low and causing the issue or my injectors are clogged or not supplying the same supply as the others.
Help me fella's! I have faith.
