My Car Is Idleing all weird,at first we thought it was the idle air control valve
but I replaced my IACV and its still idleing all weird,
when my car is running my RPMs Jump from 1500-2000 Non Stop

What Could Be The Problem??I dont Think Its a Vacuum Leak

also

My friend Checked out My car and my CEL came on
we got
code:
1- O2 Sensor
3- Map Sensor
6- Water Temperature Sensor
16 -Fuel Injectors

Would any of these Codes have anything to Do with the Weird Idleing?

Sum1 Help Me

a faulty o2 sensor can cause a rough idle.
a faulty MAP sensor can make your car run like a total bag of crap.
a faulty injector(s) can make your car run/idle crappy.
Check those 3 things for sure.

I would also check the fast idle thermo valve (fitv). There is a little wax peice that is threaded into the body of the valve, these like to back their way out and cause a rough/jumpy idle. All you have to do is remove the 3 screws that hold the backing plate on and tighten the little wax peice thats threaded into the body of the valve.

MAP sensor can do that in a big way, so can the water temp sensor for sure.

anyways.... I definitely don't "NV" your EF
