I was going out last night,in the SC, which had set in the garage for at least 4 min. warming up in the 95 degree heat. I then backed out of the garage and turned the A.C. on, backed down the drive about 60 feet into the street. Put it in drive to take off and it had a huge power loss stumble for a couple of seconds, I then too off, drove the car with the air on stopped and started and it has not done it again. I put 10,000 miles on the car its tuned up with new plugs and wires and the only other complaint is an occaisional 1400 rpm ever so slight miss.

OK I reproduced the same event as the other night but the car did not warm up quite as long. I thought it had to do with backing out as I usually pull out of my drive. Today when I went to take off after backing out, there was no hesitation. I have been advertising the car for sale and feel bad about it having an intermitant hesition, when otherwise the car runs perf.

Sorry for bumping my own thread but, I left out this afternoon from work, 92 degrees, and with the air on until the temp. needle came to half way ,my car sputtered a lot. Once it warms up it runs like new. Just wondered if anyone else with a 95 has this problem. Def. way worse with the A.C. on. All tune up done and no CEL. Fuel filter 9000 miles,clean MAF wire.

try get a computer check anyways. my CEL wasn't coming on, yet it was throwing a code when they checked. can't hurt right?

Peace out

Sounds reasonable to me, sure would be nice to have a plug in code reader.

I assumed the IAC was only responsible for idle, and the car idles perf. even when cold.

I typed in [ check engine codes on an sc400] and got no reply by the search button.Could someone tell me the easiest way?

I had bought some gas at a no-name gas station, and then I put a half tank of brand name and it seem to make a huge diff.
