You might want to check for any possible vacuum leaks from the back of the intake manifold. A severe enough vacuum leak will cause the engine to spit and sputter. You may also want to check the egr valve stuck in the open position as well. Also caused by possible vacuum issues. Vacuum within the intake will increase with accelaration and if you have a cracked line it could cause the symptoms you are describing.

Good Luck

SOURCE: when the engine is not cold, it idles at below 400 rpm and stops

have the throttle body cleaned it is restricting air flow from having to much carbon in the intake yes and also it is time for plugs and wires.

1991 Honda crx won't start


Try tracing the wires and looking for a worn spot in insulation that is grounding out, its a royal pain but might be the only solution, use wire prob and test areas where inaccessible. good luck

Looking to buy a 1988 Honda CRX HF. Automatic Transmission. I would like to do a 5 speed swap on it. What is needed, how hard would it be, and what would it end up costing me?


-5 Speed Transmission

-Clutch/Pressure plate/Flywheel/Hardware

-Clutch cable

-Manual pedal assembly with same options as your car (Cruise control2_bing.gif for example)

-Front, side, and rear transmission mount brackets from 5 speed car, and the actual mount for the rear (Regardless of what people say, it is not needed to drop the rear x-member to do this rear mount, but if you don't have a decent set of tools, you may have to do this to get to the rear bolt.)

-Manual axles. I think auto axles will work.

-5 speed throttle cable to match the the 5 speed pedal assembly

-Auto speedo cable will work.

-Connect the 2 larger black wires that go to the shift position switch in the automatic. These wires are for the starter. In the auto car, they are only connected when the car is in nuetral or park. Solder these two wires together and heat shrink. Use a **** connector if you want to just ghetto rig it together.

-You will get a code 19 and a "check engine light". This is for the torque converter lock up solenoid on the PS9 auto ECU (For my D16A6 Motor anyway, the 1.5 may have a different auto ECU). The car will still run and drive fine, but getting the manual ECU for you car, and cutting off the auto wiring from the harness will eliminate this issue.

-You will need to ground the Green/White wire from the shift indicator switch, this indicates that the car is in "park", and will allow you to remove the ignition key. The alternative is to swap to the 5 speed ignition switch, but you may not want to end up having separate ignition, and door keys if your car currently uses one key.

I have a HF 5 Speed ecu and a few other parts to if you need them

Price is hard to tell because of price of parts and places vary to do these swaps. Shops around here will covert a auto to manual for anywhere from 500-800 bucks labor only.

the wiring harness rubs in half. trace the wires from the alternator back. Under the intake manifold about middle ways you should find the broken wire.

Car bogs under 2000 rpm but runs good above 2000 rpm


Sounds like the Altinator is going out. At higher RPM it is putting out enough power to keep the car running but when the rpm gets below a certain point there is not enough power coming out of it to keep the car running.
