2003 Volkswagen Jetta

Had to pass state inspection, got new tires at pepboys, they didn't balance the tires, went back, changed thermostat due to check engine light, soon as I left, cylinder misfire, they claim it was spark plugs, reset the code, drove fine for about a week, car lost power all 4 cylinders misfired plus mass airflow too low. Changed out 3 spark plugs, the last one is hard to reach, same thing. Some of the hoses were wrapped with duct tape , one was coming off after pepboys broke off a part, depressing, not sure what to do.

First posts normally go in introductions else you could get a free fix and we never see you again!!!

Default Welcome to Volkswagen Forum - Rules & Recommendations

Don't use pepboys if they don't balance wheels after fitting tyres and can't remove spark plugs without breaking something.

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing.
