vacuum sits at -16 at idle.
IAC was cleaned when it was put back together. I'm going to take it off again and re clean it, and maybe lube it.

I don't like to drive it too much, seeing i still don't know what the A/F is at.

 

I'll come up next weekend with the wideband and we will see what its running at!

 

Are you going to show up this time??? lol

I don't think you are supposed to lube the IAC Valve!!!

 

if it doesn't rain! can't really check it in the rain

 

The hunting idle may be due to improper base throttle plate adjustment....the car would need to be driven for at least 1/2 hr for the fpdm to overheat and bog/miss fire (dtc 1232)...

 

ok, well we can count out that right now, it has never driven more that a half hour.

but i will try going for more than a half hour and check it out.

Thanks for the info.

What is the next step up in Fuel pumps from a 255LPH? i wanna stay intank.
Or what should the 255 be good till (HP)

 

255 is the biggest intank that I know of!

 

I'd say the idle issue is likely a IAC or T.P. problem, could also be as Nick said, the base idle not properly set. A vacuum leak could also cause this but it should set a code pretty quickly. As for the fuel pump, does the code return immediately? maybe it's just a bad pump and is shorting internally? I'd first confirm no wiring damage/routing problems and then get a new pump under warranty. If you wanna go for a drive you should be fine as long as you drive easy, a lean condition usually shows up in the top end, do you have a code reader or hand-held tuner?

 

[QUOTE=Ponyryd;83785]I was thinking IAC also, but now that you mention the T.P problem, i know that i have to snap the throttle to get it to come down after driving it. also push back the throttle when under hood to get it to come down more. but that does not explain why it would go up and down when the fan kicks on.
Vaccum sits at -16 at idle.
no it does not come back on right away. i would say 3-5 minutes before it returns.

 

The fuel pump voltage on returnless cars are controled by duty cycle (via fpdm) and if the pump is not compatible the pump will draw more current shuting the fpdm down..setting the 1232 dtc...its not the fuel pump size thats the problem.You need to fix this issue first...
