i swapped a 98 d16y8 into my 99 ex it was missing a vacume line. i spliced the line into another one. it has been running fine till recently and my check engine light is on now i got it checked it said it was the idle speed control. my cruise does not work. the idle is real high when i first start it in the morning till it get warmed up then its fine. When i push on the gas it jerks and when i let off the gas it jerks but when the gas is on it ok but sometimes it jerks real bad when i'm goping slow but in a low gear. i need help so if anyone can tell me whats up it would be appreciated

 

that happened to me once and it turned out to be a sliced wire on the o2 sensor, i don't know if thats ur problem but mind as well give it a check

 

kinda sucks cause its illegal to put an older motor in a newer car. happen to a friend and say hello to state ref and say good bye to ur motor being in that car

 

oh and to help u out, mine did that also, turned out it was the dizzy. is it throwing any codes? theres a idle control valve on the intake mani and if u clean that out it helps a lot too.

 

he lives in pa so he doesnt have to worry about that

 

ok, not to interupt this thread, but what is that rule for the older motor into newer car, or is that only for cali residents??????
thanks

 

i'll have to check those wires the code came back p1508 idle speed control is that the same as the iacv because i changed it from the one off my original intake manifold i cleaned the screen and everything and it did the same thing so i don;t think its that
