Hey guys,
A litte stumped as to why my car is bucking when it creates a lot of boost pressure. Anywhere from around 15psi and up. I have a brand new ignition cassette. I just put in brand new NGK laser platinum spark plugs. They have only been lasting me around 8,000k a set with a stage 3+ ecu upgrade. From what I know extra boost pressure results in less spark plug life. But the new spark plugs that I just put in still arent stopping my bucking issue. They always have in the past. I had an engine light blink at me today after it bucked hard. I am assuming from a bad misfire and then it went away. Could it be from bad fuel pressure? I have 119k on the stock fuel pump. Any other thoughts or suggestions?
Thanks,
James
