Alright guys, I'm going crazy with my car, I was driving and all of a sudden my car loss all it's power, at idle and it wouldn't even accelerate past 2700 RPMs. So I got home checked and replaced my plugs and nothing. I then checked my timing and it's perfect. Checked compression and have 180 in each cylinder. Replaced cap, rotor and wires, still same problem. Changed distributor for one on my other cb which runs perfectly fine and still same problem. I changed the head and head gasket since I noticed it was leaking oil through the headers, dont know why, still has the same problem. I replaced the fuel injector resistor box and still no change. I thought it could maybe be my cat but when I did the head swap I took advantage of the fact that I loosened the downpipe and it still had the same problem. The only thing I have not swapped nor replaced is my O2 sensor, but I dont know if that could be my problem. Oh another thing I noticed is that the spark on three of my cylinders is not too strong, the spark on cylinder 4 is VERY powerful but on the other three extremely weak, can that be my problem and what could be causing this?

Well I really need to get my car started ASAP since I was forced to move from my home and the landlord is on my *** to get it out or he'll get it impounded. Please help and thanks in advance for all the help...

 

Spray some WD40 on the distributor to see if you have a crack in it. Had this problem on an old car. Couldn't see anything wrong until it was dark and saw a spark on the distributor.

That or take it off and inspect it for corrosion ect.
