Question about pulsing while idling
I have a 91 convt with 72k on it. It runs good, however it pulses between 1.5 and 1.7 while idling. Could it be an O2 sensor? I don't have any records for the car but I know it is recommended to replace it at 60k.
Any help would be greatly appreciated. |
1500-1700rpm???
prob a vac leak its should idle at about 750 |
How do I go about finding the leak ?
|
looks for a cracked vacume line
spray some wd-40 around, if it smooths out, you just sprayed the leaked, keep looking and you will find it |
calibrate your tps also..... (or should i say tps reports)
|
Will I damage the engine driving it this way ? The check engine light is on.
I hate to sound stupid, but what is a tps ? |
throttle position sensor
search the second gen forums for a guide to adjusting it |
