ive been having this weird problem , when its cold it runs normal but when its fully warmed up th idle sinks low. then when i take off it feels like theres a 800 pound guy in the back seat, no cels and the compression is good across the board. any ideas?

 

check your throttle cable it may be loose..just a though happened to me before.

 

Check your timing. Make sure your idle is adjusted properly. Make sure your IACV and ECU is reset after adjustment. If that doesn't work report back.

 

i've got a similiar problem but only when fully warm. Difference is my idle drops to 650rpm when fully warm. and lags when accel.

 

I would say your ignition timing could be off by a few degrees (retarded) in my opinion, given I suffered from a similar situation. My idle after adjustment sits at 800 pretty steadily after warm up now with advancement of timing.

Try advancing your idle +2 degrees and see if that cleans things up. Remember if your obd1 your service connector needs to be jumpered in order for the adjustments to take affect.

Oh, does your car back fire a touch too, when its really warm out? A bit of a "put put" here and there?

 

my car feels the same warmed up and occasionally does the backfiring for no reason. what is it?

 

I checked the timing and was set to 18degrees, although i'm not sure what the service conector is? which means I didn't do it correctly. But by moving the dizzy to 18degrees, how do I correct it now?

 

my SH has a simalar problem. when stopping and the RPM drops to an idle it sinks so low that it kills out. can anyone help me out?

 

Advance your timing a little bit and see if that helps it

 

Maybe Idle is set too low. So, Idle is OK when cold air intake valve is opened. Try setting the idle speed after warm up (recessed screw on passenger side of intake manifold).

The probable cause for the whole problem is that the timing belt may have slipped a notch. It sounds like the whole system is out of time.

 

i couldnt seem to fine the screw, got any pics ?
