I have a problem with my 93' SC and I'm trying to fig. out what the problem is. It seemed like the past month or so the car cuts out for just a split second occasionally while speeding up and building boost. It was not very noticable but bothered me enough to get a code reader (Innova yellow box). I hooked up the scanner, dont remember exactly what codes I got but know it was related to my tps was "under voltage".
Acouple days ago while driving and speeding up my SC cut out again but this time much harder. It basically felt like it ran out of fuel or spark when I hit the gas. It did this everytime I hit the throttle alittle hard, then I decided to go and get a new tps and installed it being I had those codes. After installing the new tps I starting the car and went around the block and I had the exact same problem engine cold or hot.
I had another used cam sensor which I switched but that did not help.
I disconnected the battery for about a hr hoping that would solve the problem. I then drove across the street to the gas station and put fuel in it. I then pulled out of the gas station and gassed it abit hard... BIG NO NO. Problem now got worse, car died now and would not start. I tried about 10 times and then finally started after I turned the ignition off then on again. Limped it home without throttle because if I gassed it, it would die again. The car seems to only restart after dying Only if the ignition gets turned off first, otherwise it will just keep turning over without start. I put the scanner on it again and these are the codes I got.
With engine off codes are 111-10-212.
With engine running (did not tap throttle while testing and not sure if I was suppose to) codes I got are 6-10-538.
Also the car idles perfectly until you hit the throttle then rpms will dump and turn off if gassed to hard.
Can someone please help. Thanks
