you might have a vaccume leak or the mar sensor may need cleaning if it's a fuel injected setup i really need engin size to get a better line on problem try you tube also.

how low was oil,I heard one car do not start no oil.spark plugs,air filter,fuel filter,coils module.

Yes the map sensor could be faulty.
You should also get a check engine light when you unplug it.

vacuum leak, egr valve, crank or cam sensor......

Or clogged fuel injectors . Do yourself a favor and save yourself the aggravation , take it to a qualified repair shop where they have the diagnostic tools an knowledge .

If you've recently added (or oiled) a cotton air filter like a K&N, extra oil can foul the MAF sensor causing drivability issues. Most helpful thing you could do is pull the codes though and post them on here, as it could be many things... bad O2 sensor, intake leak past the MAF, failing fuel pressure regulator (my main guess) and others. It'd help if you listed what engine your car has as well and how many miles it has, and if you have this problem under load only or even when it is in idle.
Pull the codes.

Problem is not solved but I did change the fuel filter, coil pack,ICM and have proper fuel pressure to the motor. Car starts but dies right away. I cant seem to find out if the fob on the key ring has something to do with stopping the motor. This fob says Radio Key by Secure Key with a number 35077 stamped on this thing.. Still trying to find out what this is and does it effect the cars ability to run

the rev limiter is not engaging properly

ck fuel filter could of sucked up something from the bottom of gas tank,,could have fowl spark plugs,,
