94 del sol b16a MT

ok...its throwing a CEL code 14 (idle air control problem) i replaced the IACV but it didnt help and i know there a bunch of different issues that are associated with a 14 i have had time to try some misc. fixes and im still having the following problems:

car bogs down to unhealthily low rpm's when power is drawn for normal things (heater, lights, power steering)... and when lights are on it idles at very low rpms and shakes the car. but the second you turn the lights off it goes up 2-300 rpms... i've had HID's and it did the same things. everything is hooked up properly as far as ground wires and such.

next: when letting off the gas throughout the rpm range in any gear the car jerks like you've down shifted and then when you give it gas it has a split second delay and then jerks again like you dumped the clutch... basically its not a smooth acceleration at all... and it does this in all gears.

i originally thought this problem was due to a lightened flywheel but that wouldnt explain why it doesnt accelerate smoothly so maybe this could be a fuel problem??... maybe a TPS issue?

and then i have this constant problem of the 1500-1600 rpm wobble. im starting to think this could maybe be an ECU issue. if you give it just enough gas to get to 1500 is sticks a little bit and it should hummm but it stutters ...wob wob wob wob wob. and if you give it just a little more gas it gets worse and then a little more gas and it goes to 2000 like it was stuck and you had to blow through it...???

i know most of these things are going to be a "i need to see it" deal but if anyone has any ideas lemme know.


JOSHUASE I KNOW I KNOW, YOU'VE TRIED TO HELP BUT IM GOING TO SEE IF ANYONE ELSE HAS REVOLUTIONARY IDEAS.
