Hi!
I have 1993 explorer 4.0ohv.
When i start "over night" cold engine, idle is pretty rough and misfiring (exhaust says tsap tsap... tsap... tsap tsap...).
Runs cold 5 cylinder? or less too but not allways. When engine warms up, it runs 6 cyl i think but idle is little bit waving and little bit missfire. On higher rpm it wont misfire.
Mpg is normal and i get these fault codes:
Engine not running:
53 Throttle Position sensor too high - TPS
66 Vane Air Flow (VAF) or Mass Air Flow (MAF) signal low - VAF MAF
Transmission Oil Temperature (TOT) signal low (possibly grounded) - Transmissions
95 Fuel pump: open, bad ground or always on - Power / Fuel Pump Possible bad fuel pump ground or open between fuel pump and pin 8 at PCM (Fuel Pump Monitor signal) - Power / Fuel Pump CircuitsCircuits
Engine warm and running:
35 EVP - Engine RPM's too low to test EGR system - EVP / EVR - EVP sensor signal is/was high - EVR / PFE - PFE sensor signal is/was high - PFE
53 Throttle Position sensor too high - TPS
85 2.3L T/C Automatic - 3/4-4/3 Shift solenoid - Transmissions
CANP solenoid (ALL 1989) - Solenoids
What i do first? (New spark motorcraft platinium plugs and wires are coming btw)
Second part:
How i can get dashboard thin panel off? (that which rounds climate control panel and rear defrost switches etc).
And how i can remove door panels? I wanna but new speakers rear and front + but lights on window-central lock panel.
Sorry bad language im not born to english speaker!
