Engine Mechanical problem
1995 Saturn SL2 4 cyl Two Wheel Drive Manual 160000 miles
Just bought a used vehicle last week and I have had several mechanics try to figure out what's causing a problem and haven't yet found out the reason for this issue I am having.
1995 Saturn SL2 Twin Cam (Original Motor)
When idling everything seems to be ok and the rpm guage reads right over 1000. The second I press the gas(slow), instead of the rpm's rising they drop down below 1000 for a split second before actually raising to 2000. When this happens it literally sounds like the car engine is trying to die out. Sometimes when manually pressing the throttle switch from under the hood it doesn't do it. Only sometimes and usually tries to die out when pressing the throttle slow. I have even stalled out several times because of this prob on the highway. One mechanic said he thought it was the map sensor but I changed it and that didn't help. Another mechanic said he thought the carbon had built up in the air intake unit therefor was effecting the throttle which I don't know if he's right or wrong? Does anyone know what in the heck is causing this issue? Any advice would be greatly appreciated.
have the same problem?
