Whelp! '91 244 seems to have the chills (shudders!)
Last year, I did a major (for someone of my skill level) project on my '91 244. A lot of you on here chimed in and helped me along in getting my car back together
By the time I had the car buttoned up, I could only drive it for a week, maybe two before she went into winter storage. During that time, the car would stutter and stumble and struggle to accelerate. During that time, I refilled my gas from less than half a tank to full and it seemed to make the problem go away. Based on what I read in older threads, that typically meant the in-tank pump is dead or about to be dead.
I finally got her out and this past weekend drove about 230 miles without any problems. Drove her right till the gas gage was just above "E" and no issues. Filled her up at Costco (where I've been filling up for years) and within about 20 miles of the fill up, same issues.
Bucking, shuddering. Weak acceleration. No CEL up until this point. Pulled the car into a lot, shut her off and unplugged the AMM. She started but shuddered and then eventually evened out. I decided to drive a 1-2 miles like that to back home. About 0.75miles away from home, the stumbling became really bad and I pulled over to the side and shut the car off. It smelt like the car was running lean. I say running lean, because, it didn't smell like gas (which I understand is an indication of it running rich). Au contraire, it smelt mildly burnt.
Plugged the AMM back in and didn't clear the CEL. Drove the car about 7-8 miles since then and it runs fine. However, I cannot clear the CEL.
OBD I codes that are present:
1. 1-2-1
2. 3-2-2
Does this mean that I had a failing AMM and that unplugging it was the final straw?
Side note: For the past year or so, the car would need to be cranked longer on a hot day after it had been driven and it hesitate some before it would have a smooth idle. This specific behavior was present before I did all the work on the car. FPR is a new Bosch unit from last year. 4 plugs, 3 wires (I f'ed up one while doing it) and distributor were new as of 20K miles ago.
