I just swapped in a d15b1 outta a ef std and the idle surges when its warmed up and then the idle drops to low and it dies... i sparyed carb and choke nothin... cleaned my iacv nothin... checked all my im and tb bolts nothin.... calibrated tps nothin... but heres my lil catch... there is no timing cover on the motor at all and i had to put a belt on it so i just used a flathead in the spark plug hole to find tdc and timed it for what looked right and it runs fine... also the manifolds
(intake) are very differend (mpfi - dpfi) so im not sure if i could even put my intake manifold on this poopy motor... well it pulls pretty hard at 8.5 psi but i cant drive it without it diein... im goin to get a new iacv right now and c if that helps but the car dosent wanna die at all when i unplug the tps... so im just confused as hell... please help

 

iacv is not the problem just puth the new one on... dont know maybe tuning cuz im runnin really rich... was a jdm d15b before now just threw in what i had layin around...
