first i aplogize if this issue has been previously addressed.
started to drive the car was vibrating, almost as if it was going to stall and the check engine light was flashing.
[b]Flashing light is warning that problem could catastrophic problem that would kill a catalyst... repair it now..
drove a bit and stopped, started the car and now the check engine light stays on constantly.
[b]Can be driven with light on, provided there is no drivability concern.. but this in essence makes you an emission violator.
I have had the light come on (and remain on) a few times in the last while but it is usually solved by tightening the gas cap.
[b]Light on, code is in PCM until manually cleared with scan tool.. Light on for trivial code will go off as there no real danger to driving with problem detected. Light may come back on as reminder or if problem detected in 2 consecutive drive cycle where PCM see same fault occur.. Tightening fuel cap is not always the cure.. how do you know it had an EVAP code ?? EVAP only test when when drive cycle criteria been met. There is a whole lot of codes that could be toruble.
Someone suggested maybe i had dirty gas in the car and needed stabilizer.
[b]Then it would be problem through out entire load of fuel.. fuel pump at station has large filter, you have inlet filter and primary fuel filter on the car.. stabilizer ?? Thats funny,, I dont even use Sta-Bil in my own stuff. Hard to get bum fuel these days, too many controls on the product.
My boyfriend said its a "misfire" and to change the spark plugs.
[b]Dont see plug related misfire concern with the 3.3/3.8 engines.. alot of money and time for a wild guess.
Anyone had this problem?
[b]Seen oil control valves get stupid and goof the cam timing to give rough run... Valve is something like $150 (US) for each bank, 1 is minor labor to replace, bank 2 oil control valve requires removal of complete upper & lower intake to replace, figure maybe $290 (US) labor, add a handfull of intake gaskets, scan tool time
I dont think there are any stores in canada that will run free diagnostics so i want to avoid paying a stealer for that, if possible.
[b]Free to guess at some expensive parts and labor, or pay for scan/diag to find which circuit the PCM has determined to be at fault.
|stealer quoted me $99.95 to run diagnostics|
|Even if you bought a scantool, got the codes and decided not to tackle it yourself they are going to charge that fee to do their own diagnostic to determine the problem.|
