Serious Engine Probs
OK, my 93 Prelude Si 2.3 has been running fine at 106k miles then one day I'm driving and around 3000 rpm it cut in and out a couple times. My clutch is bad, so I thought it was just a little slippage.
Couple days later, it cuts in and out again and the car starts to rough idle, and a lot of back fire at idle, then it stalls at idle unless the revs are kept up. At one point, the car wouldn't even restart until I waited for awhile. Anyways, after awhile it ran normal again.
Thought it was my egr, since I was getting a code 12 (egr failure) on long freeway drives, so I plated the egr, the prob went away but then came back in a couple hours of driving.
These probs are really occasional, but I am thinking along the lines of fuel injector or fuel pump probs????
The coil, plugs, wires, fuel filter, cap, rotor are all new. The distributor is about 2 years old. Timing was also recently done, as with valve clearances. Any input would be great, sorry for the long post.

thats what I was maybe thinking, but if it was a vacuum leak, the problem should constantly be there. Also, I think my car runs a little better when a have 1/3 tank of gas, but I don't have a dyno to confirm that.
I think the fuel pump may be going, cuz if it was the relay or injenctors the problem would be constant.
