Okay, my 88 is occasionally prone to bad idle. I will slow down for a red light, but when I step on the gas, the RPM's drop below 1000 and you hear this "bogging" sound.
I have a few theories:
1. Bad spark plug(s)
2. Clogged fuel injector(s)
3. Bad MAF
I do use premium gas and always warm the coolant temp. to at least 150 before I drive.
I replaced the O2 sensor a few months ago and noticed a instant improvement in throttle response, but it didn't solve the idle problem.
If the MAF went bad, wouldn't I get a "service engine soon"???? That light would come on at 70 MPH+ before I changed the O2, but hasn't happened since so I'm assuming that the O2 sensor isn't the problem.
