runnin rough

[Ameer Antar]

if your getting that many errors...it's gotta be a loose ECU connector or 
bad connection between ECU and those sensors.  Check the ECU connector and 
make sure it's tight. See if it changes anything. If not, disconnect it and 
do a continuity test to the right sensor. The Bentley has all these steps, 
but a wiring diagram would help too. The ECU is in the pass. side in front 
of the door. One or two screws holds the cover.

Don't waste time trying to check the o2 sensor...if it's older than 30k or 
???, then change it, esp. if it's a single wire sensor. Another thing to 
check is for vac. leaks. Follow the intake hoses from the air cleaner to 
throttle body and make sure EVERY hose is in very good condition. Move the 
hoses around too, b/c many times the hoses rot right under the clamp, so 
you think the hose is ok until you move it or take it off. Vac. leaks cause 
poor running, but I'd definitely check to see why yer getting so many 
sensor errors. good luck.
