I have a 1990 ls integra and everything passes but the rpm idles to high at 1100 and i can't get it to go down. The car uses to idle back and fourth until i adjusted the distributer but it won't idle any lower. From what i know the car use to be an automatic and was switched over to a manual.

Specs:

It has the stock head but a dif traning. i dont know the numbers . so all i can say is it was modified from

OBD 0 Head which i think use to be a automatic. to a
OBD 1 Tranning which i think it said if i remember PR4 on it.
IF theres anything else u guys would like to know that would help tell me and i check the car.

Im thinking the ecu was a stock. Would that make any difference? Besides that everything is pretty much stock.

does anyone know how i can lower the rpm down to 800. I already adjusted the idle screw and everthing else by the idle. Can anyone help? Thanks.

You're thermostat might be bad. Make sure you Idle Air Control Valve is clean as well.
