im in the process of doing a b16b in a 2000 civic ex coupe. the problem we are having is when the car is idleing and u push the gas pedal it shuts off. we are running the civic type r ecu. any help thanks i think its a vaccum leak but everything seems hooked up. the only wire thats not hooked up is the blue wire which is tack output. by the way we are using the 2000 ex wire harness. any help thanks

Do you have any CEL's coming on at all?

You might have a big vacuum leak, or the IACV is potentially dirty.

I would recommend you see if there is any CEL's, also make sure there is absolutely no vacuum leaks, and also clean the IACV located at the front of the Intake Manifold.

Simply take it off and use Brake/Carb cleaner to clean the screens and then try it again.

yes there are cels we haven't check those yet. some times the car doesn't stay on for that long mabe 5 secs and then shut off. also when we start the car the cel is not on anymore. thats what i tought vaccum leak but all the lines are connected and we did clean the iacv. its a strange problem

 

Yeah, make sure the TPS and the MAP sensor harness plugs are not backwards.

Check the CEL's. You may have some fux0red up MAP readings that is throwing off the idle.

 

we have to check to codes to find out whats really wrong the tps and map sensor plugs are hooked up correct. thanks alot

 

NP, keep us updated.

 

update on the problem we checked the codes. they are map sensor, tps, and iacv. we cleaned the iacv codes still came up. we used the map sensor of the sohc code still came up. what can we do now since we know what the codes are? how do we go about solving the problem.

 

Make sure the MAP and the TPS is not switched.

Also did you switch the TPS or take it off at all?

Make sure the sensors are good, and try replacing the sensors AFTER verifying the wiring.

Unfortunately, I do not have the OBD2 pinouts off hand. I would recommend you grab a digital multimeter and verify the wiring that is assigned to the correct pin-outs.

 

we did check to see if if the map and tps was switched everything was fine there. we didn't touch the take the tps of at all yea we are going to use the multimeter to find out the correct pinouts. hope we get this car running good. thanks again i'll keep u updated
