Ok, I am not so familiar with this little "pregnant roller skate" of my girlfriends. She has a '93 Honda Del Sol. A couple days ago it overheated from a crack in the tank of the radiator. I towed it home and repaired that. Now, when it gets up to running temp it dies every time she steps on the brake the car dies. The idle (once warmed up) is at about 200. When she initially starts the car it is at 1000. I have: removed and cleaned the IACV, replaced the PCV, checked for vacuum leaks, bled the radiator. A couple weeks prior to the overheat I had replaced the plugs. The wires, cap, and rotor all looked good and were replaced only a couple months ago. I checked for a head gasket issue by checking the plugs, and no water in the oil, or oil in the radiator (after the overheat). The idle adjust screw was found to be maxed out, unable to set it any higher, and the timing (by adjusting the distributor) is about right. I am out of options to check. Any suggestions?

 

idle is too low.

maybe theres and adjustment screw @ the throttle plate are to bump up the idle.

 

wow I remember my crx doing that with my old d15b1.. anyways my fuel relay and the dizzys rotor and coil had a lot to do with it granted the engine was about cooked by then.. but I'd check there first on the coil which I know autozone can test to make life easy and not do it yourself. Also, is the ecu throwing any codes?

One other thing..plug wires, my mustang had the worst problems with idle wacked out out till i replaced those, would those happen to be the original? Not saying that they would be the cause but if they are aged and brittle could have something to do with it along with a fuel filter checking.. either way if in doubt on the fuel filter change it out anyways their cheap insurance of future problems.

All I have for ideas that are easy to check out and shouldn't cost ya anything to get that coil checked rest of them you can inspect for yourself but again ecu codes would be best if any are being thrown.

 

Ok, will try that. and no codes from the ecu.
