Ok, I have spark and I have fuel coming out my injectors. The dme was sent to rogue tuning to have my logger and tuner installed and he tested before he sent it back. It seems like it wants to start but backfires and sputters instead. Spark plug wires are in the correct location and timing was checked again. I have a m-tune kit so josh walked me through checking the maf and map sensor. I'm stuck!! What do I check next? Could this be a 02 sensor or tps? Any help will be appreciated.

Might be unrelated, but i know when i did my last rebuild the two plugs on the back of the intake manifold came loose and cause a similiar issue, i plugged mine back in and it started right up.

If you have spark then the DME is firing. That means the ref sensors are working. Are using using the base MTune bin? If you would like, you can email it to me and I will look at the bin. shawn@refresh951.com
