Check engine light...

Car started to idle rough. While stopped at a red light or stop sign the engine will stall. I have to keep on the throttle to keep the engine from stalling. Check engine light came on and threw codes p0018 and p0021. Will be calling the dealer tomorrow. Has this happened to anyone else?

How is the car after restart? Keep us updated.

Tuned or stock?
Ive had a couple codes on mine, but nothing to do with the cam position nor timming. Good luck and keep us informed.
i hope its an easy fix too. Issue remains after vehicle restart. Vehicle is stock. No tune.
I had a similar issue. Dealership replaced spark plug on cylinder #2 . Worked well for about 3 months. Check engine light came on again yesterday I believe it's gonna be the same problem again
Do any of you guys get a sulfur smell after hard acceleration?

Why does the plug need replaced? Wonder if its fouled with oil and thus you might also have the cylinder head issue.

Well good news (somewhat) is that neither of the codes you're getting are listed in the SSM for an automatic engine or heads replacement.

From those codes, looks like you might just need a crankshaft position sensor. The second code is too much timing (which would be caused by the bad crank pos sensor).

I've never had a sulfur smell after hard acceleration.

Big smile yes. Sulfur no.

I don't smell it nearly as much as I used to on cars
I am behind. Maybe people are just driving slower (NOT!!!!!)
