hard acceleration=stalled out
 

so this weekend i went to George Washington Nation Forest ande when i was there my runner started acting up. but whenever i floor it now its ok until i let off then the damn thing shuts off. i cleaned the filter and it still does it. ive got about 127K miles and i think the belts were changed at 64K miles or so. i need some help cause it gets annoying.

So.. does it start without any pedal, or do you have to floor it then too? When it dies, does it diesel for a bit first or just immediately go? Do the gauges go dead as well? What about the dash lights?

In general... Plugs, wires, fuel filter, air filter. Any chance that something got sucked into the intake tube? Are all of the vaccuum lines connected?

um when i start it usually it starts for a second then dies again and i do that for a few times. somtimes i have to rev it to keep it from dying, guages are fine and nothing happens to the dash lights

Huh, had that happen on my Chevy work truck once and it was the O2 sensor had died completely.

I had this happen on my chevy work truck also, and it was the ground straps in the engine bay.

Is something unplugged?

Could be a vacuum leak too... CEL on???

:help: im sorry for the dumb question but what is the CEL

check engine light :great:

oh ha thats obvious.... but no the light isnt on.

c'mon guys i need some help

Id say Fuel Pump try some quality Fuel pump/injector cleaner.

99SR5, there have been some really good suggestions made to you...

Have you checked the 02? checked for vacuum leaks? What is the tune up condition like, Pulgs and fuel filter mostly? Any pending computer codes? Fuel pressure? \

There is a great list of things, most have already been mentiond in this post, we are trying to help, but you have given us no feedback on the suggestions we have made....

In the 3 days since you started this thread and the last post you made, what have you looked at or checked?

i cleaned the air filter and used some injector cleaner but it didnt do anything. there is no vaccum leak cause the CEL isnt on. how do i check the O2 sensor

Dont always assume that the computer knows all.... you may have enough of a vacuum leak to keep fuel trim within "allowable peramiters" but still cause drivability...

the only good way to test the 02 is with a graphing mulitmeter.....

If you are 100% sure there is no vacuum leak, I would next seee where your fuel pressure sits...

How old is the fuel filter???

Is it a K&N filter? did you allow the oil to sit a while before driving it?

i didnt use that cleaner i used a spray but after it stalled out. it still did it after i cleaned it. how do i check for a caccum leak. is it possible for that to happen if my belts are old and slipping

No, belts will not affect that....

to check for vacuum leaks open the hood and listen for a hissing sound, it may be loud, but it may also be less obvious. A can of carb cleaner is also a good tool of this. If you sprat the carb cleaner towards the area you suspect to have a vacuum leak, and there is a vacuum leak, you should notice a change in how the engine is running.

should i try cleaning my t/b with carb cleaner

you should try looking for the leak.

cleaning the TB will not matter imo.

clean the MAF?
