Gross Polluter Repair in Murrieta
STAR station certified to test and repair gross polluter vehicles.
A gross polluter designation means your emissions measured well above the allowable limit and the vehicle must be repaired and recertified at a STAR station. We are one.
Gross polluter failures usually trace back to a failed catalytic converter, badly skewed fuel trim, ignition misfire or an air injection fault. We test to find which, rather than replacing the most expensive part first.
