well i have determined that its not the crank angle sensor i thought (hoped) it might be. it only happens after its warmed up. so im thinking it has to do with the IAC or the maf or something along those lines. runs like a champ until its warmed up then i get hesitation in the lower rpms and it runs like *** if i try to pass someone on the freeway. almost like im at half power or something. any ideas guys?

 

Any recent upgrades?

 

nope. did a pop charger about 3 yrs ago ( i think..maybe a little less) but it has only been running like this for about 5-6 months. its very frustrating. its not in safe mode as i drive it daily...just feels very laggy when i punch it

 

i have the same problem but i happens all the time hot/cold. everytime i hit the gas it lags then catchs at higher rpm's.. anyone besides us have this problem?? if so, what fixed it?

 

try cleaning the MAF?

 

Im having the same exact problem with the lag. Doesn't matter whether it's hot or cold.

 

I heavily doubt this has anything to do with it but when was the last time you cleaned and oiled (or replaced) the air filter on your pop charger?

 

i dont care about everyone elses problems. this is my thread so gtfo!!!












jk hopefully we get an answer and it helps all of us!!

 

bout 2 weeks ago for oil and about 4 months for the filter. didnt do a thing when i cleaned the filter though...

 

 

worth a shot. some people run those things into the ground and starve the car for air.

 

I'd like to hear a resolution to the problem!

My car is an 04 w/ 32k miles, stock except for a popcharger (6 months old) & AAM test pipes. My car isn't how the OP described, more so like what the others have said, it hesitates whether warm or cold.

My diagnostic list tonight will be...

Clean Air filter
Change Oil
Reset ECU
Spark plugs? I thought maybe the car is running rich because of the test pipes and might have fouled out the plugs?

I guess I'll report back if any of these things help.

 

GL. ive done all but the plugs and i still have the problem. ive come to live with it...i just hate feathering the clutch to even get it going from a light when it starts with the power loss thing...

 

Have you tried switching back to the stock intake? You might try that and see how it goes.

 

Well, my car hasn't done it for a little while. Hopefully it healed itself...

 

Did you get after market led lights?

 

could possibly be your flywheel sensor is going bad

 

no aftermarket bulbs, tried switching intakes to the stock and didnt help, and why would the flywheel sensor cause this?

 

Take out your MAF sensor and clean it properly.

 

done that. its nothing obvious like that (except maybe the plugs, which im doing this weekend as i misplaced my 10mm and needed a new on lol) only thing im thinking it could be is the plugs (hopefully), or a sensor somewhere. (not the maf)
