I am having trouble with my marauder jerking(sort of misfiring) when pressing the gas pedal, mostly when I really press it. Its interesting because it jerks under light load when I fill up my gas tank every week.
Anyhow I've taken it to my local mechanic who after numerous tests told me the catalytic converters especially on the right side rattled when hit. They concluded those should be replaced.
I had to take my car to another place because they didn't weld. Upon arriving at the weld shop they tell me there are codes from the check engine light responsible for causing this issue vice faulty catalytic converters. They told me I have to replace mass air flow sensor and possibly 02 sensor. 02 sensors are relatively new. The codes that appeared were p2195, p2197, p0113 and p0102. I cleared the codes and now after driving only p0113 and p0102 are showing.
These codes have been there since I installed my headers about 2 years ago. I started having this jerking problem after those codes appeared. I think the problem lies with something else, possibly the catalytic converters. I've driven the car with the MAF plugged in and unplugged but the car still jerks. So one can deduce that the MAF isn't the problem. Does anyone have ideas what could be the problem? Could it be the fuel pump or fuel injectors? Any help would be greatly appreciated. Thanks.
