They're pretty cheap, go to autozone or advance auto parts, they should have some. I dont want to under-estimate but I'd say its under 50 prolly more like 25

How exactly is it running could be something else?

Yes like Seppuku said, how is it running? Is it idling ok, starting ok, running ok period, there could be another culprite.

Is there a way to manually adjust the fuel pressure? I run at 46psi...I have a vortech FPR, RC Engineering injectors, and Walboro 255lph..



I am trying to have my friend find the disc to lower the fuel pressure on the FPR, it's the kind where you have to change the entire disc to lower the fuel-pressure.



But if I take it out...any suggestions on how to lower the fuel pressure if it doesn't change?

Isnt that what an FPR is for, to adjust and regulate fuel pressure?

It idles good but the car shakes a bit and when you bring it to redline, it doesn't want to idle. you have to rev it up to 3 a couple of times then it will be ok. It also idles at like 600 rpm. Is that too low? It may also be some bad fuel cause when I drained the tank, I only drained part of it. I figured the bad gas was on the bottom and the good gas I put in it was on top.



Another problem I had was this morning I woke up and went outside to start it up and it took for ever to start. When it did, it reved to 2500 then died. I could keep it running but I would have press the pedal to the floor. I finally just quit. Maybe b/c it was just cold cause this morning was really cold.

the redline issue sounds like tps, get it set and should have no problem. The cold issue could be vaccum leaks. Idle should be 750-800.

Where is the tps and what should I do to fix it?

I started it up today and it began to run extremely rough! It took me forever to start it and when I finally got it to start, it would rev up to 2000rpm then die. I was able to keep it from dying by pressing the gas pedal halfway until it reved up. After doing this for a while I guess it warmed up and stopped reving but when it would idle, the car shook madly and it constantly backfired! Do you think this is the timing or still the tps?
