I have a 1992 SSEi thats stalls when you come to a quick stop and stalls when turning onto a street while going down hill. It also is lacking pick up and go power. These are the codes I am getting:
69- high pressure switch circuit
88- pcm reset
65- cruise control servo position sensor
68- cruise control command problem
67- faulty cruise control switch
99- power management problem

My mechanic who fixed the last issue I told you guys believes that the lack of power is because of a clogged catalytic converter but I dont know what to think. Please help me with this. Thanks and Happy Thanksgiving[/u]

The stock fuel strainer on the pump in 92 can and will cause stalling on right hand turns and other situations.

I don't think the A/c or cruise would affect driveablility. I would begin by checking/cleaning the battery, cables, ground, pcm connector, and sensors and their connectors if you can. My wifes car had a hesitation that took a while for a code to come up, it turned out that cleaning the MAF fixed the problem. She also had another problem before where the car would die like yours; tightening the battery terminals fixed that. I hope yours turns out to just as easy to fix.

92 fuel tanks are also missing baffles the later tanks had. This makes the strainer even more of an issue when it gets clogged.

But I also agree with the CC diagnosis and the electrical checks. These are all good points.

Battery terminals are both fine. I'll check the connectors when he opens on monday

Each end of EVERY cable. Not just the battery terminals. Most problems come from a ground.
