ah i see, to bad i dont have 93 here, and i def dont want to keep buying a couple bottles of additives for each fillup, if it wont go away with my next fillup il have the dealer look into it.

It should be fine on 91. Have you got around to filling up your tank with fresh gas? Definitely sounds like you’re describing a misfire. If it continues on the new tank of gas I would take it to the dealer and maybe even get them to check your spark plugs and coil packs and make sure they’re getting good voltage. Hopefully it’s just some bad gas tho and your problem goes away. They filled my truck with 87 when I picked it up from the dealer and the truck ran like shit. Wasn’t too happy about it

Wow. I wasn't hammering mine since it was brand new but had no idea what gas they had it in I had filled up 91 three times after that and been noticing the slight jerks but I filled up chevron this time around and haven't noticed anything. So I went ahead and installed the tune as the issue seemed to slowly go away, and I sent them the logs they said it looks perfect It rocks on the tune ! No hiccups no proplems just feel like I got new turbos on it lol ecp on the e30 map

I thought it might be worth mentioning here:
Misfires, cleaned MAF and fixed.

Just in case the oil on your air filter has screwed up you airflow sensor, you might want to spray the sensor down with the cleaner that has been specifically formulated for it. I think NAPA carries it. IF that's solves the problem, throw that oiled filter away.

That's nice, but the engine doesn't have an airflow sensor (MAF) at all. It has absolute pressure sensors and in basic terms, the airflow is estimated based on the manifold pressure, the actual throttle plate position (not the pedal) and the rpms...

It is quite accurate if the initial Volumetric Efficiency (VME) calculations are set up properly.
