I have a 89 crx dx rewired for multi-point fuel injection (pretty much an hf now). Durring a drive the other day the car reached 4k rpm and the engine just bogged out as if I had let off the gas and the throttle wouldnt respond untill it hit 1.5k and then it would start to respond again. Now every time I get to 3.5k it will do the same thing in first gear and 2.5k in second gear 2k in third. It idles perfect and throws no ecu codes, gets spark, no detonation, just boggs down. Im thinking fuel pump. What do you think?
