Get the code read.

It sounds like a fuel delivery issue. Something may be clogged in your fuel line or your fuel pump is dying. It can also be MAF related if it's out of wack.

But we'll know better if you get the code read first.

Check for misfire codes. 300, 301, 306 etc.
Make sure plug wires & coilpacks are healthy if you find random misfires.
Check CPS
Check fuel pressure at the Schrader valve on the front fuel rail. s/b 3.8bar or 55psi while cranking. If not check for clogged filter or lazy fuel pump.

Good luck.

What codes did you get for your check engine light?

getting the code read this monday

Well once you get the code read, you can post it here & we can help you diagnose the problem. It's more than likely a sensor or something.

carmichael15

thanks a lot!! keep you posted.

carmichael15

codes are,P0300,P0302,P0304,P0335.

Cylinder 2 & 4 needs either new spark plugs, spark plug wires or coil packs. Might even be fuel injectors but I doubt it.
You also need a new crankshaft position sensor.

My mother's ML does the same thing as your car (hesitant to start). It's more frequent at gas stations. The CPS needs to be replaced ASAP.

also, if you just replaced all your spark plugs, check if cylinder 2 & 4 spark plugs are tight enough.

will the check engine light turn on when you dont have freon in the compressor?

carmichael15

can someone tell me what is the function of this part? and what is it called? im missing mine!!

blzdout

No, the check engine light would not come on. Is yours still coming on? You've mentioned you had P0302 & P0304.

That thing in your engine bay is just for drainage I believe. Nothing serious.
