Misses under hard acceleration. WHY? Ideas?
Just did head gasket and studs. After assembly i turned up the tune a little. Jumped on it a bit, got a bop, bop, bop kinda miss. Or maybe its a pop, pop, kinda miss. Idles fine, runs fine under light pedal too. Only misses when I hit it.
Only thing I can think of is valve lash was a little loose (I notice while re-assembling) Figured I adjust valves later after running a while.
Any Ideas?
A look below will show the mods.

Got 250,000 miles on it.
The LPG is lame. about 40 hp around town. I never use it while racing, nitrous IS the way to go. 300 hp instead. LPG was a waste of money. But I keep it. Now putting methonol injection on. After I fix valve miss, if thats what it is.
That job was a pain in the ***. had to pull off both turbos, 2nd CP3, Exhaust manifold bolts are killers to get to.

I assume the gasket I pull off was factory. The new gasket I put on was OEM cummins. Maybe new gasket was a few thousandths fatter, giving me more lash.
It was a 5 layer gasket that cummins uses. I dont know. I'll try adj valves first. I had an idea they were a little loose when I re-assembled. BUT LIke I said, its an easy adj, compared to R&R head gasket.
What can I say, $ was an issue, I joined the other 10% of america, unemployed due to the oil spill in the GULF. Drill-Ban.
