95 Service Engine Soon
Well, on the unusually cool morning down here, changed out the MAF on my '95 hunting Service Engine Soon light problems that won't show up testing. Wierd that the engine stumbles idling with in gear and ac on with light off, but runs better with light showing. And, Jumping for code on speedo does not show anything. So, changing out part by part. That seemed to help but not cure all the way on my 20 mile test circle. But, when I run the car up to about 80 and let it coast back down to the 55 mph speed limit, light clears for a while, but later, comes back on. But, that old one was one dirty , nasty unit. So back home and just changed out the MAP valve and disconnected battery for a bit to clear anything in computer. Another test ride soon.

Not sure but have two new ones as the next step.
Just in from 2nd 30 mile test ride and same problem. If I really get on the gas on the open road and let it coast down, the light does go off and stays off for quite awhile
So , next step is changing the o2's. Maybe in the cool of the morning. ;-)
