94 acts really weird
Hey guys, I'm really hoping y'all can help me out. I have a 94 bonneville (vin L) that stutters and shakes when the torque converter locks up, and bogs out above 4,000 RPMS. I've given it a tune up, tested the coolant temp sensor, MAF, TPS, replaced the coil packs and module and no difference (although when I replaced the o2 it helped). I was thinking it was the crankshaft sensor but i know when that goes out, it goes out completly. The SES light is on, and if you disconnect the battery cables to reset the ECU, the SES comes on immedatly. I had the code checked once and i can't remember which code it was, but the tool and the book said it was an o2, sesor 1, bank 2, or somethin like that, it only has one o2 so i thought the book and the tool where giving me the wrong info since it'* an in-between year (OBD1-2, i had the same problem on my '95 blazer, OBD2 conn. but you had to read it with and snap-on OBD1 scanner with a special plug that had "keys"). Anyway I've been stumped on this car for over a year now. If anyone has any clue PLEASE help me.
