I've run with the MAF sensor disconnected off and on for years with no problems other than the constant CEL. I've usually just plugged it back in for bi-annual emissions test or when a trip to the the dealer was scheduled.

It's time for the emissions test again - plugged in the sensor yesterday, car started, but then sputtered and died as soon as it was shifted into gear. Felt like it was out of fuel.

Unplugged the sensor, took it out on the road to warm it up. Pulled to the side of the highway, reconnected. It would run OK for a few seconds or up to a minute or so, then sputter, cough, shake, grind, etc....

Please help if you have any ideas. Need to get it working really quick, for at least long enough for the inspection. I'm leaving in less than a week for a month long road-trip, and would really like to have valid plates when I do.

When I get back from the trip I was already planning to clean (or replace) the EGR in conjunction with some GDE tunes and a Euro TC.... but, I really don't have much time to get into it before I leave.

I'm gonna hook up the scanner today to see if there are any codes, but since this is on my '06 - I'm not real confident that the scanner will choose to communicate today. It's usually hit-or-miss.

Thanks
Doug

When you plug the MAF back in, the EGR and FCV valves start to come into play. One of those devices is choking the engine, you just need to figure out which one is doing it. You could try unplugging the connector at one or the other of the devices, then trying to run it with the MAF plugged in.

I would start first by getting some MAF cleaning spray at your local auto parts store and clean the sensor.
