Hi I'm a new user with a problem thats gonna give me an annurism. I
have a 1994 camaro z28 with the lt1. When i try to accelerate any
harder than gently... the car bogs down like only half the engine is
firing until it hits like 2500-3000 rpms then it kicks in just fine
and pulls great. But this problem has cost me a major loss of take off
power. The only was to break the tires now from a stop is dropping the
clutch at high rpms. The only mods i have is a cold air intake and a
straight pipe in place of the cat(i know i know.. its not the most
legal thing to do). And i had also changed my plugs about 2 months
prior to these problems. I have no idea what this could be.. can
anyone help me?
Check the fuel pressure regulator isn't split. The car is probably
running rich. There is a vacuum hose on the manifold to it. If the
rubber inside splits, it allows fuel to leak into the manifold.
The other thing to check could be the ICM (Ignition Control Module) .
Mine idled fine but wouldn't rev past about 4K.
