Most likely a throttle position sensor/circuit problem. Scanner can check this rather quickly!!
You bet! Also, this problem may NOT set a code but a scanner can read the TPS to see what it is doing. Trans. shift and idle are VERY dependant on the TPS signal!!!
Didn't find what you were looking for?
