hi, I bought an EEC tester - got a few codes:
KOEO hard code 565 (saw in here I should have the canister purge circuit tested)
KOEO stored: 327 (EGR valve position sensor, Pressure Feedback EGR sensor OR EGR Pressure Transducer - signal voltage too low)
KOEO stored: 337 (same as above only too high)
KOER 538: Insufficient RPM change during Dynamic Response Test. or, Invalid cylinder balance test - throttle position movement. or, Invalid cylinder bal test - cylinder identification problems.
I believe the KOEO codes are wiring probs. I got a carfax last yr and see my X was in 2 crashes. I see where paint is different on left fender under the hood & have seen paint peeling off the roof near the rear door. I assume it was a front and a rear crash. Carfax couldn't clarify. I know there are intermittent wiring probs w/windows getting stuck up or down. HAHA the other day I pressed the up button on my stereo and the pass rear window went down - I thought maybe someone slipped me a mickey somewhere... I've had the truck 2 yrs. I want my cruise control working! I know how hard it is to identify elec probs. I owned a bonneville from electrical hell once!
Back to the codes here. I am most concerned about the cylinder code.
Thanks in advance for any direction. Short on money here so between you all and my Haynes I will attempt my own diagnostics/repair. No, I have not changed plugs/wires but did buy them today on a hunch.
