This morning i started the car it was pretty cold outside. I let it warm up for 3 min and i started driving. I got to main street and i floored it and passes 4000 RPM in second gear. Then right after, i changed it to nutural and apply the breaks and RMP went from 4000 to almost 0 and car started shaking. It almost turned off but it came back on. wats the problem?

what yr is the car? what motor do you have and how many miles are on it ?? then we can figure out what your problem is.

[Stanglover1250]

its a 2004 v6, 3.9L, and i have 42000 miles on it.

hmm ive had problems like this in the past with high mileage vehicals and brand new vehicals do you rag on it alot by chance cause when ever this has happend to me i have ragged on my vehicals or its just old but in your case it could just be that it wasnt all the way warmed up and do you have any mods on the vehical??

[Stanglover1250]

The only mods i have is cold air intake and magnaflow catback. everything else is pretty much stock. But i haven't change my spark plugs or my fuel filter. Im planing on doing it this month.. can it be that?

It's likely the MAF. It provides inputs that control the shift points.

is there a way i can fix it?

[Stanglover1250]

spark plugs and fuel filter shouldnt be a problem

spark plugs you would notice back fire, and it would be consistent
if it drives fine now it might of just been your MAF actin up or a little water in gas

shit who knows

how hard did you slam the brakes, and how much gas is in your tank?

i had a friend stall a car doing donuts, he thought he broke it, his car was just out of gas though.
