im on my way to AAMCO right now for a free diagnosis and a price quote.

i did a fluid flush and filter change a year ago at aamco..

what happened was i was driving home and at 60 mph the car started jherking foward and it felt like i was riding over tons of bricks, but only when i step on the gas.. if im going downhill and just letting the car ride it out it is as smooth as can be and feels like nothing wrong. but when i sit at a red light with my foot on the brake the car jumps and the rpms go from 0 to 1000 to 0 and so on untill i step on the gas and it goes kinda slowly at first but it goes and it jumps no matter what speed. but the car still drives..

Try getting the MAP sensor checked. My wifes van did something like that. Didn't shift right, idled real bad, no power, ran kind of. It'* worth a look.

MAPs didn't show up until 1996. At least for PCM purposes.

First, lets check your kickdown cable and make sure it'* adjusted correctly. MAF sensors have also been known to contribute to funky driving conditions.

Your PCM will not pull trans codes...you have very little in the line of electronics in there...just lockup TC.

Hmm...lockup TC...was this feeling more like a "chggule" kinda feeling?

ok i pulled some codes before i go to aamco. here they are

code 34
code 39
code 42
code 44
code 48


so now i will go change the ignition coil, the module and the maf and see what happens..

If this is has been covered, I'm sorry. But check all your battery connections, both ends. Make sure everythings clean and tight. Also check for VAC leaks. With the number of codes you have, I would check those first.

ITS YOUR MAF SENSOR. Thats what the LN3 does with a bad maf is either not run at all or it will be going down the highway and for no reason will JERK HARD and then fine for another while. mine did the same thing.

i dont see what made you think it was the transmission?

if you've got those codes, i wouldn't doubt the damn thing is jerking

just so you know, those codes are thrown as a result of the malfunctioning maf. that should fix it all.

make sure when you get one, if you get it from a jy, make sure to clean the filaments, GENTLY with a q-tip and some alcohol.

im 110% its NOT the maf as i have unplugged it and it ran the same. i switched it with 3 others i have and the same issue persist..


you would not believe what the peoblem was..

i am charging my camera battery and will post a pic in a lil while..

can anyone guess what it could have been.. its an easy but hard guess..

OMG I know what it was!!!!!



Somebody put a FORD badge on it



hmmmm, I am gonna guess vacuum problem?

ICM retaining nuts loose? Corrosion under the ICM?
