    yes you can turn the distributor and see how far off it is from where it should be originally. its not hard to do and takes just a few minutes to determine just how far off the timing is. you may be able to set it to a different setting and make the vehicle run better for awhile but im sure its in the timing

  • Ronnie Houston Jan 30, 2009

    if you turn the distributor slowly you may be able to find a setting where it will run better...if the timing chain is going it will go regardless of how far off you are or even if you are right on the mark, if you set it 180 degrees off and it s sluggish then move the distributor slowlt towards the passenger side til you find the area it runs the best in for the time being until you are ready yo tear into it

  • Ronnie Houston Jan 31, 2009

    no you dont need to

  • Ronnie Houston Feb 04, 2009

    i would go ahead and put it in 4x4 until you can figure out why its acting like it is...i would recommend you take it to a shop since its hard for me to diagnose the whole problem from here

Car cranks but wont stay running

Only a few things will cause a stalling first is crank position sensor and second is the mass air flow sensor followed by the fuel pump or relay. you need to first find out if your fuel pump output is 45psi i it has good fuel pressure then i recommend you replace the crank position sensor.

My fiancee's grand am stalled out on her the other night and won't restart. It acts like it but just cuts out as soon as you release the key. I've replaced the fuel pressure reggulator and has a new fuel...

I would test crankshaft position sensor. If coil packs are getting power, then crank sensor should be good. If you are getting spark to all cylinders, then check to make sure you are getting fuel to all cylinders. If you are, then you most likely have a bad fuse or relay that needs to be replaced. Is the fuel pump relay ok? Fuel getting to all cylinders?
