I have a 1990 CRX HF and it has a B16A1 in it. I have had no problems with it until about a month ago when I started to get a hesitation. Between 3000rpms and 5000rpms just normal cruising (not getting on it) it hesitates and the car fells like its going to die until you floor it. It happens when the car is cold and when it is hot so it can't be the O2 sensor. The ECU isn't throwing any codes, I have replaced the rotor, cap, wires, spark plugs, fuel filter and the TPS. I just checked my fuel pressure as well and it was fine (32). Does anyone have an suggestion's what it could be? I was thinking maybe a coil that's going bad or injectors. Please help.

 

sounds like your 02 sensor wiring is reversed. just double check it against this picture before you try anything else.



if its not it, at least you can eliminate that.

 

no wiring good check that already, but thanks for the suggestion. Any othere ideas?

 

my brother had the same problem with his civic. he ended up changing the whole distributor. try swapping with a friend

 

what was ur old motor, if it was a dual point make sure u swapped the wires around on the tps (the outside 2 need to switch spots)

 

He has an HF he said. Besides, can anyone show any truth about swapping the TPS wires?

It sounds to me like your TPS "Throttle Position Sensor" is bad. I had similar problems when cruising and I swapped mine and problems went away. Check Ebay. You can usually find a couple of them for around $30 a piece.

 

my firend's coil was bad in his b16 when he did the swap. i believe its a 94 del sol part.
