okay i ran my codes.. Somone beat me over and i got a automatic p28 for starters which sucks

IM not throwing a code for a tps sensor but i think its bad.. my idle is jumping up and down harshly..

Im not sure what my car is doing but when im cruising say 40-50mph and i let off the gas the car doesnt feel normal.. feels like my throttle body is complety shutting and then when i slightly touch the gas.. the car like jerks like im putting it into 1st gear .. Ive never had this problem before i want to take it to my mechanic but if i can figure it out or get a better idea i can proably fix it..

iacv, take it off and clean it out with wd40 or brake cleaner. i had the same problem.

thats what i would need to do for the car reving up and down. what about the horrible jerking problem? anyone know.. could timing be a degree off?

my car jerked horribly, i had an ecu problem that was screwing up the iacv.

JeffBro

get the right ecu first. automatic ecus control the iac differently and this could be the problem...

yeah don't run that auto ecu too long, you'll kill your LS/Vtec - gotta take good care of that badboy.

ALright thanks guys imma start with a virgin p28 5speed 1st.. and see what it does from there.. im only throwing 3 codes.. o2sensor a vtec sold code and a code for auto trans. or something so i guess this could be the problem. I didnt think of it before cause i ran the same ecu with a b16 swap and never did this jerking but will see.
