Ok, I'm hoping that I could get a little help.
Within the last few weeks I have cleaned the TB, sprayed some decarb stuff down it's throat and drove for about an hour with the filter off(just messing around to see what would happen). Since then I have been since experiencing some kind of popping/backfiring-thru-the-intake kinda sound and stuttering until 2500 rpm's.
When I had the filter off, it would die when I took it out of gear to come to a light. After the second time, I put the filter back. The car died twice after that, but didn't run as bad.
I took out fuses 4 and 11 to reset the computer, let it sit for about an hour, put them back and after about 5 minutes of cranking, it fired up. I let it run for about 20 - 25 minutes then drove it for 30 mins around town. No problems at first.
Now, it's doing the stuttering thing mentioned above. It only does this in first gear and doesn't matter whether it's cold or been driving all day.
BTW, it's a 98 SVT.
I've checked all the intake hoses, plug wires and MAF.No codes either or other performance prblems. I did a search and didn't come up with anything definitive. Any help is greatly appreciated. TIA,
Mike
