93 3.3l
Hi, I have a 93 custom I'm TRYING to bring back from the dead(hardtimes). I've replaced ICM, coils, plugs, wires, O2 sensor,batt, alt, cleaned up batt and ecm grounds and flushed trans and unplugged TCC.
This car is evil, it shakes and will occasionally cut out and is very hestitant. It is definitaly running rich and smells of gas out exhaust(no leaks though).
I hooked up a Tech 1 and there is no codes. All of the sensors are good even tested them with a voltmeter. The only thing is the new O2 sensor voltage goes up and down erratically from .1- .9v. The scanner displays that the car is running lean, which its not. I don't get it is it a bad ecm, timing chain, cam etc... I know I've got a bad motor mounts as well. Does anyone know how to do a simple inj. test as well, they are getting proper voltage.
The car is very hesitant when cold and runs like a toilet when it is warm. though at a steady mid rev it sounds and runs good out of gear. Thanks for reading, I guess I'll give it another go tonight!
