I have a 93 gt and the computer keeps throwing a lean code but the thing is that my car is running way to rich like raw fuel and idols rough in the low rpms also if you rap the throttle it takes a little bit for it to settle back down to the proper rpm. I cleaned the icm, the egr and the maf sensor and even got a new maf meter. I have heard of others having this problem but no exact cure for it one person said fuel filter other said bap sensor. If you guys have any input that would be great thanks.

I've got very similar symptoms and codes, are you getting codes 41 and 91 too?

Its also got this ridiculous idle condition that won't let the RPMs come down at all after it starts warming up. They stay around 1.5-2k the whole time regardless of being in gear or having the clutch in. While driving, it almost feels as if cruise control is stuck on a little, but I know it isn't. I've heard this can be due to the VSS, IAC, or maybe the TPS. I've checked TPS voltage and sweep as well as cleaned the IAC, don't know how to check the VSS in the tranny tho...

Please, anyone have some experiential input?
