Hey Everyone,

My 02 Carrera II drove perfectly up to a few weeks ago; I had to go out of the country so it sat for 2.5 weeks (was started for me once during that time). I just drove it again and it drives really rough until it gets to 3K. It almost sounds like it has huge/lumpy cams on it and the power delivery is not linear. Any quick checks I might do or do I need to take it somewhere? It even threw a check engine/drive to workshop display for a second. Thanks in advance for any advice!

Sounds like coils to me. I would check all of the coils for cracks. If it is time for plugs, I would change all of the plugs and coils. If a threw a code like that, it sounds like a misfire.

Thanks for the replies guys. I thought it might be plug/coil related (the car has 47K miles) but the timing of it is what threw me off (that it happened after sitting for 2.5 weeks). Oh well, guess I have to take it somewhere to have the codes read and spend more money on it!

And it was my girlfriend's father who started up the car for me... hmmm... <_<

When mine did the same thing, (less than a week after I got it) it was a loose plug/coil wire. I went and bought the software right after that. It was $148 I could have spent on better things than to tell me I had a misfire on plug #1 and a 10 min fix.
