ok, so just try and drive it as much as possible to empty the gas tank? Should I pull the injectors and make sure those are ok? Also are the injectors from a 99.5 A4 the same in the 01 A4? I know they have different engine blocks, just wondering if the injectors are the same.

check the ICM and ECT also. they aren't too expensive and easy to change

 

00+ do not have icm's......... when are people going to realize this?

and i think onepoint8tee said in another thread the ect shouldn't cause a miss

also i would look at his maf, give it a good cleaning with electronics cleaner, or if you guys have someone in town with an 01, maybe yours would work too, but try swapping mafs

you might even try unplugging it and replugging it back in see if it drives/idels differently

 

An ect can cause a static miss-fire.

 

Yep, I'm with the ECT theory as well. Easy swap and cheap part that can only help the situation. Examine the coilpacks when you do the plugs, too. They might need to be replaced or possibly at least some new electrolyte grease or whatever that stuff is.

 

blinking cel dose not mean misfire it means stop turn of car because you are causing damage to the catalytic converter

 

Do seafoam BEFORE you change your cats.. Or else your going to run all that **** through your new cats and clog them up a little...(Or a lot if you have a bunch of ****..)

 

Flashing cel does mean a misfire. It means a misfires is occuring that can cause severe cataylasit damage.

 

The ect can cause a misfire as well till it reads a normal temp. Check your mafs like said earlier. Pull codes that will get us down to buisness

 

I think your on the right track with trouble shooting, but it sounds to me that either your fuel filter is clogged or the fuel pump is struggling ( which will cause not enough fuel to get to engine and cause it to run lean )
its easy to replace the fuel filter ( and cheep ), do that first. if that doesn't fix it, i would get someone to check you fuel pressure. Hope this helps!
