lean and misfiring after warmed up

[viperdiablo]

all the plugs except #3 are white so they r runnin lean, but #3 is wet. i switched plugs ..wires..checked the gaps..checked that the wires are on right..im getting spark and fuel, i have a small vac. leak, but it only misfires after its warmed up.

it ran fine til we did a compression test, then it started acting up.

make sure all the connection to the plugs are correct. Both on the plugs and the coil pack.

sounds intresting that you have a vac leak only once it is warmed up. That alone sounds like a gaskit may be at fault around the intake manifold, TB area.


Far as the plug readings, what plugs are you useing? And about that wet one, was it fuel or oil that was on the plug?

i checked all the plugs and they were all hooked up right... as for the wet plug it was fuel on it.. the vac leak is all the time it just isnt fireing when it is warmed up.

Try checking your coils they may be bad.
