Cadillac 60 Special Exhaust Gas Recirculation/EGR Valve Replacement at your home or office.

Showed up more than 30 minutes late. Quickly installed both parts. One requires adjustments to maintain the proper idle. Same issues exist. Says it’s a cylinder 3 misfire. I confirm with another diagnostic read cylinder 3 is misfiring. Have sine replaced both coil and plug, wire set is new and connected to other 3. Still an issue. He said the only way is to create another appointment.

Richard was very knowledgeable about the job. He has a pleasant personality. I highly recommend him and will use him again.

Peter said during our initial conversation that he had worked on Northstar engines and based on the symptoms (stalling, hesitation at low RPMs), he concluded the problem was the EGR valve, and it may need to replaced. He suggested I order the part, which I did, but did not mention the accompanying gasket (which would also need to be replaced). The new EGR valve did improve the sound of the engine while idling, but the tachometer still doesn't register RPMs at low idle, and it still stalls. Thanks to the numerous attempts from my last stall, my battery is now dead. Although my gut and research says it is the Crank Position Sensor, $178 later (labor) I am back to square one, a car that won't crank.
