Newbie to the forum. New to the 944 with my 83 944 non turbo. Replaced the mass air flow (new) but it still run roughs when cold but it idles fine. When you get on the accelerator in sputters/rough unitl it gets warms. Once your moving its fine. Any thoughts.?

 

DME temp sensor is probably bad.

 

Thanks for the info. I will replace and see if it works. Thanks again.

 

I have replace the temp sensor, Checked Fuel pressure, replace the fuel injectors (with ones that were good from another car) and it still hesitates when you get on the gas...Any more thoguhts...???

 

I would check your fuel pressure next and see what it is doing. Might be a possible fuel dampner or FPR problem. Also, I would check the TPS with a multimeter.
