idle

Hi. I recently had my throttle body replaced. The car starts and warms up fine, but has a "bobbing" idle between 1100 and 1500 RPM after the car moves. Odd, I know. Everything is fine until rolling to a stop with the load off of the engine (either clutch in or in neutral). The engine slowly...

Lately I've been having a issue where the car will randomly run lean at idle. Some times when the lean condition happens the HPFP psi will drop down to the lower 400s. Other times pressure will hang around 420-430psi but will still lean out. At times even getting to 16.38 for a second or two. I...

My genpu has a rough idle where it makes a small sputter every few seconds, I also get a p0300 random misfire code that comes on every few cold starts. I have done everything I can think of to fix this issue. I've changed the spark plugs, cleaned the valves, rebuilt the HPFP, changed the o2...

I recently installed the Pulsar GTX3071r and the Corksport Exhaust Manifold. I kept getting P0335 code when I would start my car. I mentioned this to some buddies and @Maisonvi mentioned he used to get this code with the 4" intake before he zeroed it out at .9v and below. I am guessing I never...

I've had a slightly rough idle for a while now, no codes or rpm fluctuation, but it sounds and feels like a small sputter/pop every few seconds, only when fully warmed up. 2010 with 62k miles, injectors and valves recently cleaned. Logged HPFP pressure after turning the car off and pressure only...
