hello everyone
i have a 91 ls special..everythig stock
my problem is; it bogs between 3300 and 4000 rpm
i changed the plugs, cap, rotor and fuel filter thinking that might fix the bogging but still does it
what would cause the problem? would it be the dizzy?
any help would be great
thank you

 

mornig bump
i need some help please
what could couse this to happen?
it loses power between 3000 and 4000
maybe fuel pump? or dizzy?
please help i wanna drive my baby lol thnk you

 

anybody knows what i should do or check?
please help out a fellow Da owner

 

have you checked your timing?

 

or changed your air filter?

 

did u turn the dizzy?? it moves with time or when people mess with it causin it to misfire chek the haynes manual

 

try and find a diff dizzy so you can narrow it down to if its the dizzy or not. if its the dizzy then its either the ICM or coil

 

timing is dead center and change the air filter

check all the bolts on dizzy; all are tight

found me a dizzy and still did the same thing...im thinking fuel pump

 

Shouldn't be the pump if its only at a certain rpm, ur positive the timing is right?

 

when i unplug my tps it did that i would try that so mabie a new tps or pull ur TB off and cleaned the fast idle thermo valve and the idle air control valve and in side fitv it wasnt screwed in right so try that stuff

 

timing is dead on

ill try that today
thanks to all for the help
