codes are 20 7 and 41 car ran fine before vtec was hooked up then within a day this idle happens. like its bad im afraid to drive it now this has to be something major codes were recurring before and motor ran fine is this distributer? i have a 95 civic w/ a 94 gsr b18c1 p72 ecu

 

Code 7 for the TPS might cause your problem. If you reset the ECU, does code 7 and the other codes repeat?

Also check whether the throttle cable is too tight and whether it may be binding. And clean the throttle body as the throttle plate may be binding due to gummy build up.

 

ya I'd start with the throttle and resetting the ecu. Makes the most sense.

 

id have to say it has somthing to do with the throttle due to the fact that when your throttle is closed and your ecu sees that its ideling above 3000 rpms it cuts fuel, so check the tps and also check to see if the cable is to tight and is opening the throttle

 

code 7 is intermitent even when resetting the ecu also i moved my car and theirs about 20$ worth of fuel on the ground

 

If it's not in the throttle body check for vacuum leaks and clean your IACV and FITV. Is the fuel leak coming from under the engine or tank?

 

i dont know i dropped it off at my mechanic a day or two ago for the idle issue and they called me about the leak thats all i know it might not even be my car lol but i filled it and parked it in my driveway a day before i brought it and there was nothing in my driveway

 

do those have the fitv? on my LS the spring backed out and caused it to idle at 3500..

 

Could be a huge vacuum leak, I remember one time the vacuum line from my brake booster slipped off the nipple on the intake manifold, which raised the idle up to about 4000 rpm

 

updates?
