crx 86 si hard start problem
i have an 86 with an 89 motor from an acura d16a1, it seems to idle high at operating temp, and is hard to start when cold, have to prime the fuel pump a few times and crank the motor for a bit then it starts idles low for a few then starts to build power, then it is driveable, when the motor is warm it starts right up everytime with out hesitation and has full power, ive looked everywhere for a vacume leak, i think it might be the air idleing pump on the back of the intake manifold may be locked up?, the ecu isnt showing any codes related to the motor or that pump,

Sounds like your coolant temp sensor is bad, wired incorrectly, or both.

i didnt have it hooked up, it didnt make a differnce, i found a vacume leak, car starts perfect now
it has a code 20 now ,i went over all of the wiring and fixed all the problems and reset the ecu and when the car runs for 15 sec it loses power and bogs down, if i turn it off and start it again it runs perfect for another 15 sec, untill it shows code 20, i belive its a bad batttery ground or motor ground
