Hi there, i'm off tomorrow to the biggest wheeling trip i've organized and so today i decideded i'd try to do a mini tune up. I did the drip down intake clean thing, used electrical cleaner on the MAF and IAC and changed the oil (and spilt it all over everything!).

I was a quart short, so later on this after noon, after about driving 25km, i bought some oil and added it. Now my check engine light is on, it's not even comming off when i disconect the battery ????

Any idea's? I know it's hard to say, but maybe someone has run into this before?
I do smell a slight burning scent that was around when i was doing the intake clean, and i had cranked the engine over once without oil, to get the oil from the pump...

If you did an intake cleaning you might have gotten some fluid into the cylinders causing a slight misfire. If you pull the code it will probably be a p0300 radom cylinder misfire.
