My 2nd VX, have known the original owner of this one since new. 3000mi oil changes on Mobil1 5w30 since break in.
The car got hit and sat for 2 yrs. I had the body repaired and put it back on the road, but I'm having some idle and performance issues.
Fresh fuel, fresh filters, oil/filter changed. I cleaned the plugs, ran 2 tanks with a high concentration of Techron FI cleaner. I removed and cleaned the idle air valve. I've put about 2,000 miles on it now and no change.
Still getting a very low idle. Will not idle up with the A/C on and sometimes it idles so slow you think it's going to just up and die, A/C or no A/C. Really struggles with power with the A/C on, and I don't remember it being so bad on my 1st '92.
Went through the idle set procedure and all looked ok. No real difference to be had.
Was thinking that a tune up + throttle body clean + off the car injector service were in order.
Anybody have a write up on cleaning the throttle body? I'm a bit lost on what to do or look for.
My car sounds similar to yours, the things I know about for my vehicle is related needing a replacement clutch, but the symptoms seem similar to what you describe. I also have disc slippage in low gear, high torque, though.
