Ok, I had what sounds like a similar problem in my car that took months for me to resolve. It turned out to be the wiring harness that connects on to the dme temp sensor.
I think you should go ahead and verify that the wiring is good going from the temp sensor to the dme. On mine the wires were broken right where the boot on the connector starts. |

since you got the same reading at the dme connector as on the sensor it sounds like you are probably correct, but what I am suggesting that you do is to unplug the sensor and the dme and test the wiring that goes to the sensor just to make sure it doesn't have any shorts or breaks in it.

Alrighty, I'll do that tonight. I have narrowed this down to either my DME or the wiring. I'm pretty sure it's the DME, so I'm going to have it tested.

I just wanted to update this thread and post the solution to my problem. The problem was the MAF sensor. Here's the story: Being the moron that I am, I fried the original MAF sensor by hooking it up to the wrong side of the coil (I didn't know any better at the time). Josh was generous enough to send me a replacement and I fried that one as well. After frying 2 sensors I didn't want to ask Josh for a third, so I bought one on ebay. When it came I was super excited to get my car going, so I just popped it in, hooked it up to the correct side of the coil, and turned the key. No dice. Shortly after that I ran into the cross threaded sparkplug problem, so the NA-Tune issue was put on hold.
Once my car was all sorted out I turned my attention back to the NA-Tune. The car still wouldn't run and I figured it might have been because I installed the original chip backwards and fried it. Being the generous man that Josh is, he let me exchange my chip for a fresh one. It still wouldn't run. After exchanging a few emails he informed me that I needed to remove a resistor in the DME and install a jumper wire in its place, so I did. The problem still remained. I had my gasoline and matches ready, but I decided to take one last look at the MAF sensor before burning my car. Lo and behold the part number of the sensor I bought on eBay didn't match the number on the original sensor that came with the kit ![]() Also, to anyone that's still on the fence about buying the NA-Tune, BUY IT NOW!!!!!! My hesitation, stumbling, shuddering, etc have all been solved by this kit. My car feels like it gained 50 horsepower (I deleted my cat at about the same time) and it's an absolute joy to drive now. Make sure you get it with the 4* cam key. Tl;dr: New MAF sensor fixed it |

Glad to hear that you got your car up and running. Now you get to enjoy it again. Thanks for the update, I like to hear how things turn out. I know I probably would have set it on fire after the second MAF sensor.
May the evil 944 gremlin stay far away from your car for a very long time.

Shhh don't jinx it! I've had nothing but bad luck with this car... In the past month or so of driving it it seems to be all better, but only time will tell. Maybe this is just the calm before the storm...

That was my little prayer for you car, to keep it safe and running without problems. haha
My cars have been running good for a long time now. Once you get everything worked out they should be good for some time. Hopefully your's will.

You've been keeping that gasoline on the sidelines for so long it probably wouldn't have lit off, anyhow. Glad you're up and running. I've been chasing a stumbling acceleration for a couple of years (part time). My next thing is trying NGK plugs vs the Bosch Copper + I have now. I'm wondering if the NA tune might be the answer to all the problems.

+1 what everybody else said.
Everybody knows that the secret move to getting it fixed is just one move ahead. Nobody agrees on what that move is, exactly... Happy Father's Day, and kudos for not giving up! Now, what's this I hear about NA-tune? :-) |

The NA-Tune fixed all of those problems on my car, so it should do the same for yours. Quote:
It's great! |
