hey fellas, i need your assistance. my car KA into ae86 swap is done, i just still cant get it running right. i can start it but would have to keep my foot ont he gas to keep it on sometimes. it would bog out and die if i tried to rev it slowly but if i rev'd it fast it would do fine. so i tried running the motor with no maf, and it idled fine and rev'd, up to about 2500 rpm, obviously cause no maf, slow or fast. so i figured i needed a new maf, and it ran a tad better but still the same symptoms. so could anyone help[ me out with this one, why does it feel fine with no maf, and shitty with one. im thinking my timing could be off but im pretty sure its really close. even if it was timing, why does it feel fine with no maf. help me out guys. thanks in advance

Have to agree with the tps. I ran into a similar problem, tps fixed it.

Check your vacuum lines. There is somewhat of a rats nest of them!

how do i check if the tps is in the wrong position or if its working right? and if it wasnt working right, how come it doesnt have the same problems when the maf is unplugged.

and with the vacuums, i think i got all of em in the right places that are needed. and same as above, how come no problems wth no maf

no maf is a Limp mode. it should BARELY run without it

well it only revs up 2500, but the revs are smooth when reving fast or slow. not like when the maf is in, i can only rev high if i rev fast. but when i try to take it up slow, it starts bogging and dies.
