TPS Adjusting?

Post by boredfast »

It's strange, with the new revision I can see at initial prime, TPS reads 0%, and it goes thru the whole pedal range it maxes at 102%. The moment I start up my car, it goes to 1%.

This might be a compounding problem for my idle issues.. I recently installed a walbro pump, and my idle has gone to complete shit. I cleaned my IACV a while ago, and since then I've had to bump my IAC slider value almost all the way right. After the fuel pump install i've had to click it up 2 more notches as it just dies (on the fwy too, boy that was a fun trip starting the car up again at 40 mph before i plowed into the stopped car in front of me). Idle AF is 13.5 as I have 750ccs.

1) How do i adjust the TPS? I've read that there is a security screw or some crap like that, but I cant exactly figure it out, and since they mentioned that the TPS is not sold seperately from the TB, I don't exactly want to mess this one up. A detailed explanation woudl be so helpful for me (pictures are even better!!)

2) what's up with my IACV value? usually people have theirs within the middle range, but as my car stands right now, it is virtually 2 clicks from MAX. I have a feeling i might have damaged the valve itself... when I cleaned it, i seperated the electronic part fromt he valve part, but I read from someone's thread that there was actually an o-ring on the valve itself that needed to be removed.. I pretty much SOAKed that sucker in carb cleaner and it spun pretty freely (although not as free as other people mentioned)

out of ideas.

Have you retuned since changing the pump?

A reading of 1% should not cause huge idle problems.

I had to pull around 5-7% fuel at WOT i believe, and actually had to richen up the idle to get it to 13.5 w/ 0 to +/- 1% fuel trim.

that's IT! I wasn't sure 1% TPS was messing up my idle either, but who knows, do you think it would be worth my effort to try get it to 0 or lower?
