Hi all! I really need some help here. My husband and I are at our wits end. We have a new to us 2000 jeep wrangler, 2.5 manual. Since August when we purchased it we have only been able to drive it maybe 20-25 times. Everytime we have fixed/replaced something on it another problem comes up. So with that being said here's the newest of problems: We have an engine code p0505. Idle air control valve.
We have cleaned the throttle body multiple times. Along with the iac sensor. We have replaced the iac sensor 3x with mopar sensors. At idle the engine reads 1000-1200 rpms. While driving the jeep, the rpm is where it's supposed to be. As soon as the clutch is engaged or in neutral the rpm goes all over the place between 700-2000 rpm until we are at a complete stop. Once stopped the rpms sit at 1000-1200 rpms again. Any ideas or suggestions? We're really at a loss here.
What we've done:.
All hoses have been checked, replaced if needed. O2 sensors replaced with NTK sensors. TPS replaced, crankshaft sensor replaced with mopar. IAC replaced 3x with mopar. Still getting the p0505 code and crazy/high/erratic rpm. Help please!
