01 corolla problem need help asap

car starts and idles fine but when i try to drive it has a hard time going....if i just hold down the gas it'll rev to like 2800 or so and loops. i have a generic intake which im probs gonna put back to stock one and i was thinking it might be spark plugs but i dont know....please help

yeah, try checking your plugs maybe its fouled? no harm just to check.
I had the same problem too recently; but it was contributed to putting to much gas additive which fouled my plugs.

just changed the plugs this morning, same problem..i thinking tb dirty so if i got time later this afternoon i'll put the stock box in and clean the tb..any body got any ideas on what the problem is?

Can you describe the problem a little better? I am not sure what you mean by "if i just hold down the gas it'll rev to like 2800 or so and loops".

if i step on the gas rpm will drop low then rise up a little...if i hold the pedel down it'll rev up then loop like i got a vaccum leak ...like im steping on the gas and my car does want to go..wont rev higher then 2800

If you are not idling bad or experiencing any engine roughness when trying to accelerate I don't think this is going to be a vacuum line issue.

If the engine is smooth when trying to accelerate but the car is really slow it sounds like you have a torque converter/tranny issue. It is possible you broke/stretched a wire between the ECU and tranny while working on something else under the hood.

My car does this and it basically was two separate problems on mine. The MAF sensor in the airbox was all plugged up, and my front o2 sensor is shot. I cleaned the sensor up and it got a little better, but I still need to get the o2 done

see thats what i was thinking it was the mafs sensor cause it looked dirty i allreaDY changed to o2 sensor..i didnt what to change the mafs and that wasnt it ..is there a way to clean it or to check that its the problem

hold up. did you by platinum plugs?<br />
<br />
there is your problem if so

clean the maf with soapy water and a gentle cloth. let dry and re-install

i used autolite plugs...soapy water??...wouldnt it be better to use like tb cleaner? if not then how do you get inside to clean the wires

first... go to the dealership and buy some oem denso plugs. you're supposed to be using IRIDIUM. 2nd, fix the MAF sensor. my friend's matrix came across this problem too. you should be able to pick up a good working one from a junkyard for roughly 50 bucks.

That is the MAF. Soapy water and a cloth no... get some spray electrical contact cleaner at autozone. Do you have a CEL? The code would be P0170

10 bucks says it's your MAF.
