Haven't replaced battery or positive cable . Sometimes it starts after ten try's sometimes it will start first try. When I try to play radio or charge phone or leave driver door open that's when I seem to think I just shuts off " that also is the case when cars running " if doors are open an radio is on or try to charge phone car will run either a few seconds or maybe max 15 mins

My car will still crank and run but it sounds like i slung a rod. It smokes by the valve cover and exhaust.

I've seen ads for OBD interface diagnostic tools. I'm tired of paying mechanics for diagnostics. There are so many to choose from! Any suggestions?

Car runs rich, surges at idle until warm

I just bought it. the first codes it pulled wereP0170,P0172, and P0175. I cleaned the MAP sensor and ran a can of fuel injector cleaner through it and cleared the codes. About 400 miles later the 1070 and 1072 codes came back. It also surges at idle while it is warming up. It seems sluggish during acceleration until about 3000 RPM then clears up and takes off. Any idea of where to start??

It has fire and gas but not starting when I hold the petal to the floor it hits what could be my problem

just changed timing belts. engine runs smooth up to when vtec power should kick in. ran normal before belt change. brand new plugs turning sooty in one day.
