Thread: High idle?

Can somebody tell me what cause the idle on my car to be so high. I replaced the maf, map, iac valve, the entire air intake, the ICM and coil packs, spark plugs and wires, the ICM, fuel filter, fuel pump. So I'm not understanding why it's not running normally

being na, pull the vac line off the fpr on the fuel rail, sniff the vac line for gas, or if gas comes out of the line the fpr is bad.

No gas came out of the fuel pressure regulator

What should I use to clean the throttle body

If I start the car up with the maf plugged then unplug it after it starts. And the car don't die. What do that mean

you just learned how aftermarket mafs dont work.

Ok and it didn't die immediately when I unplugged it but it died about 2 minutes later

No when I took it out of the tb the bottom piece of the maf broke off and I'll check my vac lines again
