hey everyone, i recently swapped in a semi built a6 and turbocharged it.

when the car reaches operating temperature, the cel will flicker once, and then the idle will bounce between 1-2k.

when i unplug the map sensor, and the cel stays on, it will idle at 1100rpm, with no signs of an erratic idle.

ive been told i have a vacuum leak, so ive been trying to find it, will a vac leak only show once it reaches operating temp? is that possible?

i have a hondata im gasket, and a d16y8 im, and have all of the nipples properly blocked off, or have a vac hose on tight with a ziptie.

have checked everywhere for a leak, i just replaced my tb gasket last night (which i thought may be the cause) but it still does it.

i tried my stock ecu for a sec to see if it does the same thing, and it does.

i bled my coolant twice, and have no air bubbles.


is my map sensor bad?

what could cause the problem to only appear when the engine is warm?

 

i believe if you don't have your bov set right it can cause idle problems

 

i did have my bov coming from the tb, and it was fluttering. i hooked it up to a better vac source, and now its perfect, so the bov is fine.

anyone else?

i adjusted my valves. made sure my intake manifold bolts were tight, and rechecked all of my vacuum lines and its all good. more ideas? im gonna try replacing my map sensor. in the next few days.
