03nash Posted January 7, 2009 Share Posted January 7, 2009 HELP!!! My sons 91 civic D16A6 has loss f power when you press the throttle, it just falls on its face and pops and crack...He has checked compression,fuel pressure,replaced wires and plugs,fuel regulator,and fuel filter. He bought a new timing belt but hasnt replaced it yet. The timing is right currently, its starts and idles fine. It just has loss of power when pressing the throttle like there is nothing there.Could someon please help. What type of sensor could be causing this issue if thats the case...

quake Posted January 9, 2009 Share Posted January 9, 2009 The only thing I can really think of.....is either a ECU problem......or maybe.....an airflow temp sensor.......but then again....I could quite possibly be wrong..... Link to comment Share on other sites More sharing options...
cranny Posted January 9, 2009 Share Posted January 9, 2009 sounds like a MAP or TPS sensor problem to me. has it been apart at all recently? if any plugs have been unplugged under the hood lately , its possible the MAP and TPS plugs were put on the wrong spots as they are the same. that or one of those 2 sensors is plain outright no good. you can test them with a mulitmeter.

We were thinking maybe the TPS.Hasnt been apart other than replacing things mentioned before.This started after down shifting, after that the car just started acting up..Already changed the ECU.Its quite puzzeling.

HONDA CRX 88 SI Posted January 10, 2009 Share Posted January 10, 2009 When you turn on the car and its in idle, can you turn the throttle body slowly and will it rev or crash Link to comment Share on other sites More sharing options...
03nash Posted January 10, 2009 Author Share Posted January 10, 2009 When you turn on the car and its in idle, can you turn the throttle body slowly and will it rev or crash When Honda ran the dianostic test on it they said it was a fuel code...They said to start with replacing the fuel regulator.It is acting like the convertor is clogged but it doesnt have one.Its getting to much fuel.

03nash Posted January 11, 2009 Author Share Posted January 11, 2009 Hatch back on the road!!!!! Put new timing belt on and that solved the problem. The belt had jumped 2 teeth. Honda said they checked the timing , but they must have not checked very well...I guess we still need to replace the fuel regulator though cuz its still pumping to much fuel, but atleast its not cutting out and spitting like it was...Thanks for all the suggestions !

They checked ignition timing, not cam timing. Unless they pull the timing belt covers, and line everything up, they won't catch it. Link to comment Share on other sites More sharing options...
03nash Posted January 11, 2009 Author Share Posted January 11, 2009 Thats possible..Im just the mom here, but what the hay, I found this sight hoping to find some help and now Ive been reading everything.lol I did learn about the timing though, I said the same thing to my husband in the regards to the timing and he just looked at me like I was nuts,Honda did tell my son that it was pumping to much fuel though so hes going to fix that next.
