sounds like the mass air flow sensor is faulty

Customer: replied 1 year ago.
how do i check the mass air flow
Expert:  cloe0626 replied 1 year ago.

pull off the air duct between the air filter box and the throttle body to see how the MAF sensor is anchored. If you see Torx screws, buy a Torx tool and a can of CRC Mass Air Flow Sensor Cleaner. Don't use any other cleaners; they can ruin the MAF. Everything you need is available at CarQuest, Advance and O'Reilly auto parts stores.

Customer: replied 1 year ago.
hello?
Expert:  cloe0626 replied 1 year ago.

my only other thing i can think of is the engine temp sensor

Customer: replied 1 year ago.
i already changed the temp sensor( computer one) and the cold injector sensor also
Customer: replied 1 year ago.
do u think its the distributor or something else?
Customer: replied 1 year ago.
igniter?
Expert:  cloe0626 replied 1 year ago.

it could be the distributor is out of time

Customer: replied 1 year ago.
timing is fine but do u think the dis could be bad. how do i test the dis?
Expert:  cloe0626 replied 1 year ago.

If your vehicle's distributor is bad, the engine either won't start properly or won't start at all. The distributor is one of the main components of your vehicle's ignition system. A simple way to test a potentially faulty distributor is to use the "secondary-spark test." This test checks to see if the initial spark from the vehicle's battery is routed properly through the distributor. If it is, a spark will appear. If not, you will need to repair or replace the distributor. The secondary-spark test is performed using a spark-tester, which is a thin, long metal rod that conducts sparks. A spark-tester can be bought at any automotive parts store and should not cost more than $10, as of May of 2011, depending on the quality of the spark-tester.

List of Items Needed

  1. Put on the gloves and lift up your vehicle's hood.

  2. Use a socket wrench to remove a spark plug wire off of the distributor. Insert a spark-tester into the distributor.

  3. Start the engine and check for a spark from the distributor. If there is a spark that emits from the spark-tester, the issue is not with the distributor. If there is not a spark emitting from the spark-tester, you may have a bad distributor and should repair it as soon as you can.

Tips and Warnings

  • The spark emitting from the distributor is very dangerous. Do not get too close when checking to see if the spark is emitted.

Expert:  cloe0626 replied 1 year ago.

then the distributor is not the problem let me do a little research and see what i can find and get back to you

Customer: replied 1 year ago.
ok
Expert:  cloe0626 replied 1 year ago.

give me about an hour

Customer: replied 1 year ago.
its been more than an hour?
Expert:  cloe0626 replied 1 year ago.

ok lets check your ignition switch

Expert:  cloe0626 replied 1 year ago.

The lock cylinder usually gets a break in the wiring and this happens. Measure the resistance of the key resistor pellet at the base of the ignition key. Next, find the two-wire harness coming from the Ignition Lock Cylinder at the base of the steering column. Insert the key in the Ignition Lock Cylinder and check the resistance at the base of the column. It should be the same as the key. Watch the ohmmeter while turning the key all the way to crank position and back to off several times. If the reading is open or it varies, the Ignition Lock Cylinder is faulty. Replace the Ignition Lock Cylinder. Bring the old key to a dealer to have it matched to a new key. There are different resistor pellets available and the key and lock cylinder pellets must remain the same value.
