ok guys, heres my big prob. my car sounds like its backfiring and bogging when at idle or whenever i *** to a stop. when u look at the engine and hear it it sounds normal and its not surgin or anything. but u can hear the backfiring and bogging cumin outa the exhuast. also the rpms fluctuate between 800 to 1000 back and forth then to 1200. i cleaned the iac and checked the fast thermo and all vaccum lines. what else could this be?????
thanks,
j

I hope this isn't intentional

It sounds to me like your fuel pressure is low. Get a guage and check that.

 

and if its low what do i check?

 

anyone????

 

Everything from the tank to the TB, starting with the fuel filter?

With many things, the first question you ask is "have you changed anything lately?"

So -- if so, start looking there.

After that, could be FPR, Fuel pump..

If the pressure is low *before* the fuel filter/FPR/TB -- then I'd suspect the pump.
If the pressure is OK before the fuel filter, and low after it, then I'd suspect the filter...

Just start at one end and work your way to the other.
