Right bank seems fine, left bank is VERY rich. Soot all over the exhaust tip and black cloud whenever I floor it. It has an intermittent code 43. It will run fine for a while, then struggles at idle and the CEL comes on and then idles fine again. It has new plugs, wires, Opti, knock sensors...

1994 Automatic. CEL comes on w/code 43 when engine warms up and reaches closed loop. The CEL turns off every time after shutting off the engine. The code 43 comes on when switching from open to closed loop. Knock sensors are brand new. Wiring checks out fine. The only thing I can find is to...

Sometimes my '94 will start to surge at a stop in gear. If I put it in neutral, it stops and idles fine. I am getting DTC 43 that I have been trying diagnose. Could this cause that? Knock sensors are brand new.

I know there is a separate code for the KM failure, but I replaced the knock sensors and all the wiring checks out ok. DTC 43 keeps coming up. There is an exhaust leak under the car, but I will be replacing the exhaust anyways. I can tell by the way it runs that timing is being pulled out...

My '94 had a new opti and Autolite plugs installed right before I bought it. The injectors were checked for pulsing and they all came out OK. I had to replace a bunch of parts because the car sat for a long time. I installed new AC DELCO premium wires. It was missing before I even changed...

Any have a pic of the back side of the sport seat switch? Trying to figure out if a piece is missing. Thanks! :)

1994 LT1 - Both cooling fans are always on and do not shut off when the motor is running. Relays? Are they located on the drivers side of the radiator shroud?

I replaced the radiator on my '94 last night, which was bent about an inch or so sharply in the middle. Previous owner tagged something, but surprisingly missed the condenser. The trans fluid that came out was like a strawberry milkshake. The coolant seemed ok, but some brown crap came out...
