Engine Performance problem
1997 GMC Jimmy 6 cyl Two Wheel Drive Automatic 98.000 miles
I have a great truck on my hands that I have had many years and took exrta special care of through proper maintenance, and tune up's, oil changes. Etc. But lately it has been running a little sluggish some days then running wonderfully other days. A few people have mentioned this sensor and said this could be the issue as to why it's so back and forth. After all these years the truck still gets decent gas mileage, and starts fine. No visible cracks in the distributor cap, plugs look clean I dunno.
I while back I had a friend hook a diagnosis machine up to it and a misfire popped up in cyl. 1, so I changed all the plus and wires- computer came up with nothing after.
Any input about this would be most appreciated.
have the same problem?
