Mitsubishi dies and bogs when hitting the gas
1998 Mitsubishi eclipse 2.4 liter automatic, i took the fuel filter off and blew it out with air compressor i put it back on and it idles fine but it keeps bogging down when hitting the gas pedal then goes back to idling fine.
Sounds like if you would have a big stereo in it and everytime it beats the headlights dim down and motor dies down. But i dont have a big stereo, what could be the problem?

Re: Mitsubishi dies and bogs when hitting the gas
Did you have this problem before you took the fuel filter out, or were you trying to fix it by doing that?

Re: Mitsubishi dies and bogs when hitting the gas
I tried this to fix the bogging down and noise problem. It did seem to help the idle a little though.
It make that strange noise and does not have any power at all. Thanks again.

Re: Mitsubishi dies and bogs when hitting the gas
Well, I'd have to assume that either you are losing fuel pressure, or have a misfire condition that is bogging down the engine under acceleration. I don't have the exact spec that your fuel pressure should be, but I would still recommend doing a fuel pressure test. A pump with low flow/pressure/volume can cause a situation like this.
Otherwise, start checking the basics....check for spark on all cylinders, even under load. You may be losing it due to a coil or ignition wire, or spark plug breaking down under load. If able, check fuel injector pulse with a test light, and if equipped with a proper scanner you can do an injector balance test. Make sure the air filter isn't clogged, etc, as well as making sure there aren't any vacuum leaks.
If the check engine light is on, you should pull the codes and see what comes up, as that's probably a good lead to what's wrong with the car.

2006 Mazda mpv sputtering dies p0455, p0442 evap leak
since no mazda section i posted here, 2006 mazda mpv, been getting p0442 and p0455, small evap leak and large evap leak detected, a couple misfire dtc's that i could not reproduce after clearing, at first there was a minor stutter, got worst within weeks. after a while it was starting to stall out. in neutral it will sputter up to 2g then rev smooth above that. when in drive it will barely move when i get it moving, white smoke from tailpipe sometimes. no exhaust, coolant, or hg leak. front three coils seem fine. iac valve working. cant find/hear/ see a vacuum leak in engine compartment. if i start driving by very little throttle i can get it going fast, soon as i come to a stop or rpms drop it will sputter out/die. if its the coils wouldnt i get a misfire code?

Re: 2006 Mazda mpv sputtering dies p0455, p0442 evap leak
anyone have any ideas why this engine is acting this way?
anyone with similar probs?
fuel cap/ tank pressure sensor/ canister/ purge valve/ pcv routing problems?
could it be just a sensor issue? stuck valve?
i posted in the Ford section since they seem to have a lot of manufacture specific dtc's in common, why no Mazda section though?
any help, insight or even brainstorming ideas are appreciated.
thanks guys,
Jay

The EVAP codes would not cause the running problems you are having. You could just have a bad gas cap or stuck EVAP vent valve for those codes.
Yes, if a coil(s) were bad you should get a steady misfire code. But i have seen on other cars were an entire bank is dead, so its running on half the cylinders, will not give any misfire codes. I think because it is running so bad that the computer cannot determine which ones(s) are misfiring.
With it have absolutely no power, it almost does sound like it is misfiring on one bank. Acceleration causes a heavy load on ignition and that is usually were the problem is. Slow accel may not be enough to get a coil to break down. Maybe the slight stutter and misfire codes were the beginning of one or more coils going bad. I would check all the coils. If you can get it to idle ok, try spraying water on all of them. A lot of times this will cause a coil to fail.

2001 corolla stalls
2oo1 corolla 4am motor 16v starts then stalls after 5 sec . spark failure ....yyyyyyyyyyyyy 

Re: 2001 corolla stalls
it does this every time you start it? giving it gas doesn't make any difference? you may have to verify that you have good fuel pressure, injector pulse and spark and see what of these three turns off first. It might take some test equipment that the regular person doesn't usually have

2001 Toyota Corolla Stalls
What causes the car to stall when i come to a stop light is it the fuel pump??Or air is leaking from intake manifold help!!
Re: 2001 Toyota Corolla Stalls
if the car seems to run fine but only at stops it dies, you should look at things that affect your idle. Idle speed, idle control solenoid, throttle body coking, vacuum leak (though vacuum leaks usually will cause a higher idle than normal), if it's an automatic trans, the trans not letting the engine slip enough at idle...
if you can scan the engine data stream and watch the idle control, see if it tries to raise the idle when you come to a stop. what you want to look for is if the engine stalls because it isn't getting enough fuel or if the idle control just doesn't open fast enough to keep the engine running when you come to a stop.
From the way you describe it I wouldn't think it would be the fuel pump or a leak in the intake. But it should be checked just in case.

Re: 2006 Mazda mpv sputtering dies p0455, p0442 evap leak
I have2006 mpv have had po442 code for years, no problems. I now have sputtering dealer replaced tps no help. I tryed my spair key and running better, not perfect. I think maybe ignition switch problem.
