I have a '99 T5 with an engine light that is going on and off regularly. Light comes on during start up sometimes and stays on for a day or two. Then the light will not come on for a few days and then turns back on. I had the car in to be checked out and replaced the cam sensor and cam pulley based on the computer code it was giving me. The light was off for a while and then came right back on. The engine does seem to gargle for a few seconds at ignition - not a clean balanced start - then it settles into a good idle. Based on the strange start, it seems like it could be a timing issue with the variable camshaft. Other than the start, the car is totally solid so I'm inclined to deal with the light and leave it alone but it is a little disconcerting. Any ideas or experience with this kind of problem?

 

Is the same codes coming back up?

What are the codes?

 

My wife's 99 does the EXACT same thing to the letter. The sputters during start up about 4 out of every 5 cold starts, her check engine light is on all the time, **** poor performance too. We took it to autozone to have scanned last year and they said the code was for a crank position sensor. We replaced that with no luck. Turns out, our volvo mechanic is 99% sure it's the front 02 sensor dead becuase when he scanned it, it throws a code for fuel/air bank indicating most likely a failed sensor.
