alty319

so i took my car out last night and out of the blue it acted like i was running out of gas..just kept breaking up and hiccuping. Smelled really rich almost like the coolant temp sensor was gone and it was just reading a cold car and running rich. I unpluged the MAF and obv it doesnt rev past 2200rpms but it hunts for an idle and/or stalls out. Anyone know whats going on or had similar problems..? I just changed the plugs also..

Thanks

Rob

you are kinda answering your own question.

unplug the cts, no change = your problem.
if it gets worse... then its something else.

It could also be a bad injector. I just did a job, where the #2 injector didn't squirt.

An easy way to check is pop up the fuel rail and injectors, have a sheet of paper under it, semi crank the engine, YOu will see the injectors squirt, paper with fuel on it is good injector no fuel on paper = bad.

Remember, cars are easy.

1. Fuel
2. Air
3. Spark

So you just have to eliminate one by one.

1. Fuel - Common: Pump, Injectors
2. Air- Common: IAAC valve , Vaccum, MAF
3. Spark- Common: DIstributor, Coil, Plugs and wires, (Ignition Timing)

These are most common entities that will tend to go out.
