I found this recently on my fixer upper 91 CB7. It looks as though there's a crack between cyl 3 and 4 on the exhaust manifold. I didn't think it was that bad but now I'm thinking its causing my poor acceleration and performance. It seems as though the car has no power when you initially step on the gas and bogs down, but then it finally picks up at about 3k RPM.
Since this crack is before the o2 sensor, will this cause bad mileage and driveability? I can hear exhaust gases sputtering out of there behind the heatshield.
I do have an 92-96 H22 2-1 aftermarket downpipe thats in okish shape, would an A4 manifold bolt right up to that?
I'm trying to keep costs as economical as possible since the whole purpose of buying this car was to flip it for a profit, but I want to make it run normally.
