this morning on the way to school i got a constant check engine light and i noticed what felt like a fuel cut when i went into positive boost. on the way back from school( didnt go) i boosted and didnt feel the jump. is there any way to test obd2 with the key dance or am i gonna have to go to the dealer. i looked over everything under the hood and everything seemed to be ok. my first thought is the fuel mapper but im not sure. thanks

i don;t know much about it, but first thing that came 2 mind was the map sensor thingy for OBD2 cars...there is like a bypass or something, i would check the connections there

the year of your dsm will tell ya if u can do the key dance cha cha cha... 95-97 can do it, look under the mods link ^up there.... for 98 and 99, we suk and cant do the dance...

vector is prolly right, that or your fuel cut defender thing...

i farted on your wiki

Do you have a fuel pressure gauge? It could be a lack of spark. Check your wires and make sure your plugs are good. It will hesitate if you have crappy plugs or wires.

to give you all an update, the light has since gone off and no more fuel cut. i asked another friend with a boosted avenger and he said his Ce light comes on sometimes and goes off eventually. pretty positive its the fuel mapper. gonna invest in a vc2 i guess.

You might also want to keep an eye on your water temperature. After I installed the turbo, i started having increases in water temp (the needle would go about 2/3 up then drop to 1/2 then 2/3 then drop again, etc...). Replacing the stock stat didn't help. Once, the temp went a little higher and caused a lean bank condition which threw a CEL. I ordered the 160 thermostat from Howell and it's been perfect ever since (just a touch below 1/2 the way up on the gauge). I dunno if that could be your problem or not, but just something to watch for.
