Also you do get MAF code and random misfire codes but not until you push the pedal down far enough to make it quit or almost quit so am thinking that really doesn't tell me much other than the engine isn't running right which I already know. Also will have to get a vacumn gauge and check the vacumn |
MAF sensor could be your problem.
Are you running it with all air intake hoses on it.
Unplug MAF sensor it and see if it makes any difference.
What code no does it have?
