2010 Vibe won't Idle / how to keep my A/C on permanently
Love your youtube vids Scotty, you are hysterical! I know your gal has a vibe/matrix so hopefully you are the guy. One day the car decided to not start. Sym's: won't start when cold outside, will start when warm outside. Sometimes it will start if you keep the gas petal all the way to the floor ( I know it's fuel injected, but it works ). Car will not idle after warm up, car will idle when A/C compressor is engaged and fan is on. Idle fluctuates then will stall. Supposed low compression, according to GM dealer who flashed the computer for codes and computer failure. Car shows no codes. Car has lots of power. Fuel pump seems to work well. Replaced: sparkplugs, air filter, Timing tensioner. Help!! The car: 2010 Pontiac Vibe 1.8 Auto, 124,000 Miles.
The minimum factory specification for that engine is 145 psi, so it appears that your engine is pretty badly worn. I don't think it's bad enough though to prevent it from starting but I would not put any big money into that car.
You could try spraying some starting fluid into the intake then crank the engine to see if you have spark.
Have you checked the site FAQ entry for diagnosing a no-start condition?
