Default Re: HELP!! Au xr8 series 1 Running rough,

mechanic just did fuel pressure test.......
idel- 35-36 psi
revs- increase by about 5 psi,

no leakage when car turned off in 10 minutes

mechanic says yes spark plug lead 4th cylinder is definitely stuffed due to the heatshield spark and believes there is probably another one on passenger side that's no good
