This is a 1999 Chevrolet Venture, with 200,000 kms on it. I bought it
and it had one flaw. The intake manifold gasket was broken. I opened
it, i replaced the gaskets with brand new ones, and everything was
running perfect, but one little sound at the rocking arms came up. I
checked, and i forgot that the rocking arms should of been tightened at
45 degrees, where i only did 15 degrees. I re-opened everything, and
tighten them. But this time i also changed the sparkplugs and the
cables, and the distribuitor. Now i put everything together, and the
rocking arm popping was gone, but a bigger flaw came up. Now everytime
i accelerate it on low rpm (Parking Gear), it does some popping.
Whenever accelerated a bit, it makes a poping sound. Like i press the
gas ( and POP right away after pressing on gas). I turned off the
engine started it again, everything ran smooth, but as soon as i
started to accelerate it a bit, it would POP. At some point it started
to POP POPPOPOPOP, so i turned off the engine. Any ideas what that
could be? Too tight on the Rocking arms, or spark plugs, or WHAT ELSE
could it be!!

THANKS!
