Engine Performance problem
1988 Honda CRX 4 cyl Two Wheel Drive Manual 185000 miles
I had just bought my crx not two weeks ago, and had replaced the timing belt, alt belt, water pump, oil, plugs, etc. When suspecting an intermittent hesitation - lul when down shifting. Not too long afterward, I had almost complete loss of power under load / on acceleration driving in to work. It is like someone just turned off the power. But I get a sputter here and there, but typically all the way until it stalls.
Vehicle is equipped with 1.5L w/ t-body injection which has 2 injectors ( primary and secondary ).
I suspect that ECM is killing power to the injectors. Have not yet been able to test fuel press.
but do not suspect fuel pump. TPS tested ok. Vehicle loses power to the point that it will shut off
but fires back up with NO HESTATION. No check engine light on / no code flashes from ecm led. However, , when disengaging one or both of the injectors, it does send the appropriate signals to the ECM. Just not during the stall.
The car has new distributor- 02 sensor and fuel filter. As well as a rebuilt throttle body. What should I expect to see as far as power supply
to these injectors? When are the PRIMARY and SECONDARY active? ALL info is highly
have the same problem?
