1) Hard starting
2) Occasional drop in RPM for a few seconds at idle
3) Hesitation at low speed and low rpm (20mph 1800 rpm
4) Poor gas mileage
5) Reduced power
6) HVAC is stuck on defrost, wont blow out of dash or by feet
I know a number of these point toward a vacuum leak, but they also could be many other things. So far I have been told: Clogged Cat, upstream O2, Down Stream O2, Mass Air Flow Sensor, Air Charge Sensor, Throttle Position Sensor, Idle Control Valve. I dont have the money or time to just shotgun sensors and parts at this. The check engine light is not on, I dont get any error codes when I try the ignition test, and I had the Autozone guys scan it and they dont get any error codes either.
Any help sure would be appreciated, thanks in advance.
have the same problem?
