Need help..Cold start running rough
Hi All,
Need help. I have a 1989 GTA with a L98.
I have swapped all 8 injectors with new Eccels. I have replaced the mass flow sensor and EGR. All plugs and wires are new.
The issue I am having is...when the car starts after sitting for a day or more it runs really rough and I get a "Check engine light". Once the car warms up after a 10 minute drive, light goes out and car runs like a dream. For the most part. But the odd time, the car stalls out. Even if I am on the highway. It starts up right away after, but it is puzzling me on why? Could it be a TP sensor or an O2 sensor? Any ideas would be greatly appreciated.
Thanks
