Get into the engine compartment and disconnect the plug to the MAF. The car will run fine without the MAF (it's only used to fine tune the mixture for emmissions. I ran mine for a week while I waited for a replacement MAF).

If the car will run, then you know it's a MAF issue. If it doesn't, you know it's not a MAf issue, but something else. Either way it's a cheap (free!) test.

Good Luck,

Oh for the love of God, learn to use the space bar and return key! Your sentences are very hard to read. If you want help from people on this board please make it easier for us :)

Anyway, back to the problem. The quick and easy test that Graeme suggested will help you in the sort term. Try that and then get back to us.

thank's for your help, I have trouble again after cleaning the maf and the inside of the air box (where by the way found a lot of debris) ,the car ran fine for half a day, but, when I stop to get some groceries and comeback, doesn't want to run , that is, I crank the starter and he runs for 2 seconds and stops, so I do what you guys sugested and take the maf conector off ,and he start running again (thank's again for the advise) ,so here is the question ,IS IT POSSIBLE , IS THE MAF GO BAD ,TO HAVE THAT PROBLEM I MENTION BEFORE,THAT IS THE ENGINE RUNNING FOR JUST TWO SECONDS AFTER CRANKING AND GIVING THE SENSATION OF NO FUEL GOING TO THE ENGINE ,O IS JUST COINCIDENCE,SINCE THE MAF IS SUPOST TO HAVE LITLLE INFLUENCE ON THE FUEL INJECTION,ONLY MINOR ADJUSTMENT,thing is the car start and runs fine now (maf disconected),thank's again for the time you take to aswer this.

Yup, very possible for the MAF to go bad. When it is working OK, it only fine tunes the mixture. When it is bad, the signals it sends to the fuel computer are way out of whack and will cause exteremely poor idle and difficult start.

Good Luck,
