For the past couple weeks I have been having problems....my car would suddenly drop in RPM while I still had gas on...and then leap back up (little jerking effect)...well tonight it did it two times and then it just dropped to zero and then would not restart...any ideas?

 

maybe your engine went?

 

Dont know...thats what I need to know

 

The car itself won't start eh?

Would it try to turn over and stuff or nothing, it just doesn't do anything?

 

How long since you changed the fuel filter? Had a Datsun that quit running on me right on the freeway, put in a new filter it started right back up.

 

maybe fuel pump went
could be ignition problem
could be dead battery

 

I am leaning towards spark plugs dying somehow...it still turn but does not start

 

Could be dead alternator or battery. Try a rolling start. Or you could have blown a seal in the motor (that would be a bad thing). Could be a bad fuel pump. Or clogged injectors. I don't know. Try checking everything. Maybe a bad map sensor.

 

I say with 99.9 percent probablity that your motor is NOT blown, as somthing as simple as unstable rpms would not cause it to blow unless these symptoms started after a hard run.

 

Check MAP sensor.

 

How do you check the map sensor?
