- Customer states car was running fine but was having issues starting. Took to willettes and they replaced spark plugs and the battery and then car ran very poorly and was brought here. Car will start but audibly is not running on all cylinders. Engine power is low – at full throttle it barely gets up to 30mph. No CEL o/a, pulled in shop to inspect and smelled very strong sulfur smell from exhaust. Performed complete obd2 scan. No faults in ECU or TCM. Ran engine for a few minutes monitoring engine data, engine makes very little power and has strong sulfur smell after any running time. No misfires during rough running registered. All fuel data looks normal. Noticed Cat temp reached 540deg after about 5 min of idle time and smell from left exhaust got significantly worse. Removed spark plugs and checked gap, gap was a tad large on 2 plugs – re-gapped and re-installed. Engine now runs normally and starts easily. No CEL present after test drive. Since willettes installed plugs they took care of the cost for this repair.
