Here's the situation. I had a bad head gasket and a cracked head giving me a rough idle when cold started and leaking coolant. I got a new head, new gaskets and fixed that. The engine is running fantastic now. No stuttering at all when starting cold.

However, it's got a new or maybe old but now exposed issue. When I start it cold, the engine runs fine, idles great. The second I put it into gear it goes vroom vroom vroom vroom as the RPM needle bounces up and down 150-200rpm for a few seconds then stops. It will also do this sitting at red lights sometimes.

Any ideas? I thought it could be the transmission so I'm gonna drain the fluid and put a new filter in sometime next week.

How long ago did you get the head done? Was it done at a shop? If so, why not take it back to them, as a vac line or something didn't get put back. It could also be the iac valve or throttle body is dirty.
Did the work myself. Throttle body is clean. I meticulously cleaned it and the intakes.

When I unplug the IAC the engine idles very slowly, around 500rpm. With it plugged in the idle is normal in park.

Engine lopes or idling roughly

Number one cause is vacuum leaks so check the intake manifold mounting bolts for tightness make sure vacuum hose are connected and in good condition. then go over all the other possible causes because it was a head gasket just done . plus I do not know the exact mileage or how the car was taken care of like weather stuff that should have been replace was. So take a look at the following.

2 leaking egr valve plugged pcv valve= posible
3air filter clogged but do not think so
4 fuel pump not supplying enough fuel =possible
5 leaking head gasket check compression = possible
6 timming chain worn = possible
7 cam shaft lobes worn = possible
8 valves burned or leaking on new or the old head depending on if you installed new valve seals etc.. = possible
9 ignition system not function right =possible
10fuel injection or engine control system malfunction =possible



Thank you, I'll start checking those.

just got back from PepBoys

The code is P1309 - Misfire Monitor Fault

Google suggests the cause is probably the Camshaft sensor out of alignment.

I used the special tool to insert it and align the sensor the way it came out, what the heck.

No chirping noises and no oil pressure warning lights. Is it possible I managed to, using the special tool and the manual, install it out of time and thats causing the issues?
