theres a few different things .... (1) needs 1 or 2 sizes bigger main jet (2) dirty or clogged main jet (3) dirty or miss adjusted carb ( air/ fuel screw)
my 92 c1500 4.3 is giving me tons of issues I just put new egr throttle position sensor igintion control module plug wires dist and its still bogging down what can the next soulution be even changed fuel filter
Sounds more like you have a large vacuum leak to me.
Change the fuel filter
It could be the throttle position sensor or the idle air control valve.
spark pluggs
Yes it does.You can get to about 90 and no more.It will start bogging down.
When you press the accelerator, the engine wants to tach up right then and there... in the current gear the car is traveling in, it may not be possible without bogging the engine down, so the transmission is shifted down in order to accommodate the demand for increased RPMs while preventing the engine from bogging.
Maty be a plugged catalytic converter
Beat it with a stick./What is it, anyway?
Probably timing belt is worn out or jumped a tooth
mine does tha same thing but only when it gets hot that's probably why its boggin down my buddies cr125 does that same thing too
Sounds like fuel flow or fuel pressure. Change the fuel filter and check for good fuel pressure
