Intermittent Rough Idle
Hey guys,
So this weird symptom has happened about 3 times in the past couple weeks. When I start the car and after the initial rev-up, the idle drops to the 600-700 RPM range (auto). What happens is the RPM drops to 500ish and it gets very rough as if the engine was going to cut out.
I seem to experience during the initial cold start during the morning... but I think this has happened once or twice when starting the car after it has already warmed up.
This is only following initial ignition, and not when driving on the road.
Any ideas?
I had the WP/Opti replaced recently along with new plugs and wires. They supposedly checked the fuel injectors for flow too. Possibly ignition module/coil?
