I just bought a 91 CRX with a B16a under the hood, but when i start it, the motor runs rough and when i give it gas it bogs down and back fires sometimes, does anyone have any ideas on what could cause this and how i could fix it, please let me know.

Thanx alot,
Kyle

 

Fuel pump? Just throwing it out there.

 

The fuel pump is working thanks for the reply though, i am thinkin the distributer maybe but i dont know how to check it (if you can)

 

I have been messin with the motor all day and i found no O2 senser, it has an after market greddy header (4-2-1) on it. when i start it up it idles kind of high then i give it gas and it bogs down alot, almost to stalling, and then backfires like crazy.

 

Mine did something like this. It was a loose rotor screw.

b4 I figured this out...

Mine would run fine for months, then it would stumble all of a sudden then die and not restart.
I would mess around under the hood and it would start again.
I found that a repair someone else did was indescribably bad. The rotor was flopping around on the shaft.
They stripped the rotor screw, I can neither tighten nor replace the rotor.
I had to put some epoxy putty in the hole to secure the rotor because I was 800miles from home in the emptyness of Indiana.
I plan on buying myself a dremmel type tool and getting the rotor swapped out.
I am not sure about the threads in the shaft, but I will x that bridge when I come to it.
