Hard to start Hot
Looks like my car is getting hard to start when hot. When cold starts first turn of the key....when hot takes a few seconds with a few pumps of the pedal ....then bad idle for a few seconds revving the engine,then fine...
Thinking fuel pump or leaking injector? Probably need to check fuel pressure...anything else that's an easy check...haven't had to do much work on fuel injected cars mostly carb guy so will take some time for me to get a handle on things...

Well Pumping the pedal won't really help much. When you turn the key the pump is on and sending fuel to the rail. Your filter might be junked up. Like you said check for fuel pressure.Matt K.

That's normal. One of the temp sensors (probably air located in afm) heats up and tells ecu that it's hot. ecu calculates correct fuel amount to inject except that it's misinformed. You can wrap afm in fiberglass insulation to prevent this.84 mt 6mge with intake, exhaust, suspension, brake, and wheel mods
