This 2014 Jeep Wrangler came in for a tick noise at idle. Narrowed it down to a rocker arm on the driver's side. The noise is now gone after installing some new OEM rockers!

A Jeep Compass came in for a stumble/stutter around 60-70 mph. I found the misfire counters increasing when the stumble occurred. The next step was to pull the spark plugs and check the gap. I found the old plugs were sitting at .070", spec is .041". Got new plugs installed after checking the gap. The stumble is gone and ready to go back on the lot!

Recently a 2016 Jeep Wrangler came in for an oil pressure light and related codes. I found that the connector for the oil pressure sensor was shorting the 5 volt reference circuit. This caused a handful of sensors to not read correctly including the crank sensor, throttle position sensor, oil pressure sensor. Picture of the connector in the comments.

Had a 2018 Explorer come in for a dead battery. After charging overnight I was able to run a parasitic draw test. I found an aftermarket remote start module causing excessive amp draw causing the battery to die after a few days.

I had a 2015 Chevy Trax come in for some driveability concerns and check engine light. I found the spark plug gap was over double what it should be causing spark blowout while accelerating. The check engine light was caused by a degraded catalytic converter. After replacing the spark plugs and converter this car is ready to sell at the local dealership!

This truck came in for the AC not working. The customer had the system extremely overcharged thinking it was low. After some diag and getting the charge amount correct I found the pressure switch was bad which was the initial problem. Shortly after replacing the switch the compressor went out, it was likely damaged from such a high charge. Got all that replaced so the ac can blow cold again!

I recently performed diagnostics on a 2011 Nissan Armada for a check engine light, air bag light, and no air conditioning. I got the blower replaced to fix the air conditioning, replaced the vent valve because it wouldn't seal, and replaced the clock spring for the air bag concern. All the lights are off so it's ready to be put on the lot and sold!
