No, I have set and reset and double checked the tps voltage and it stays set at .54. I am on my way to return the MAF that didn't fix it so I might as well try to get a TPS. I'll post the results in a few hours.

Just to check again....have you adjusted the throttle body-blades-so that the iac is about 20 to 30 counts warmed up at idle?
Also did this problem only start after mods, and what are your cam specs?

I adjusted the base idle and set the tps voltage. How do I see what the IAC count is??

If Rich(prior owner) is reading this: Any idea what size cam you put in here???

Thanks

drive it

You need a scan tool to read iac counts etc. Does it lope considerably at idle?
As stated before-you may well need a reprogram to get rid of a false code 33.....

Yes, it lopes like crazy. It runs great when cold but as soon as it warms up, the codes show up, the idle starts loping and it has no power.

drive it

OK, lets try this....cold idle-what rpm is it and whats the vacumm at? Then when warm-rpm? vac? And so as to reference the vac. reading-what elevation do you live at? Lopes when cold and warm?

It is working right now. I replaced the TPS. I think the timing is off and the idle is still crappy but it is not going into "limp home" mode anymore. I am going out to adjust the timing back a little (it is pinging just off idle). I had it set to 8 BTDC. I think I'll bring it back to 6 BTDC ( or fwd depending on how you look at it).

I think it needs a custom prom to clean up the idle a little more but right now it is running and not stalling out. I can't get it all the way down to 400rpm in drive. I have it at about 500 right now and it doesn't stall out.

I don't know the vacuum levels (no gauge) but will be mounting a gauge for that soon.

I think idle should be 525 w/out A/C and 650 with.... I just think that 400 is way too low. :seeya
