i got my car back. got 3 problems.

1)i have to turn the ignition like 5 times in order for car to start? any reasons?

2) finally when it does turn on, it revvs itself up to like 4500-5000 rpms. any reasons?


i just installed lt4 hot cam kit, port and polished heads, 2400 stall, suspension stuff, jet hot long tube headers

 

#1) That could be your fuel pump, hook up a fp gauge and see how it does. If it doesnt hold pressure (like mine did) when you turn the key to the "On" position then the pump could be bad. Also after you get it cranked leave the fp gauge on it and pull the vaccum line off of the fp regulator real quick and see if the pressure starts to spike if it does plug it back in quick, that means that the fp regulator is working still.

#2) Could be the TPS sensor or IAC. You need to hook up a scan tool and see what kind of voltage you are getting from the sensors. Either that or you have a vaccum leak.

 

well...i dont have the tools to check the volts on either the IAC or TPS, but any ideas wher the vaccum leak is coming form? pictures or sites i can look at?

on that pic there..you will see a hose (to intake manifold port under throttle body) can that cause my car to stumble? or to revv up the way it does?!?

 

If there is a leak, then yes that will cause a high idle by letting un-metered air in.
