Hesitation when accelerating
Hello everyone
I'm having a problem with my '89 corvette coupe...when I'm in "drive" gear, I get a rough idle and also when I'm accelerating, I get a lot of hesitation. eventually the speed will pick-up, but the hesitation is very nagging. I want to take it to a shop, but before I start paying I would like to get an imput as to what the problem might be. thankx in advance, everyone.

Re: Hesitation when accelerating (akisana)
Have ya changed the air filter (real easy), loosed the snorkel from the TB and sprayed a pile of TB cleaner(most difficult is spraying with one hand whilst wiggling throttle plate with the other), ran a bottle or two of fuel injector cleaner through it (grandma can do it), or changed the plugs and O2 sensor(I do this as a set).
You might have done all of this but you gave no information as to what you tried.

Re: Hesitation when accelerating (NUckINg FuTS)
First thing I would look at is the ignition; cap, rotor, plug wires, and plugs.
You'd be amazed at what a simple tune up will do for ya!BTW, :seeya Welcome to the forum!

Re: Hesitation when accelerating (War Machine)
Hello again to everyone who responded to my question. I tried cleaning the trottle body, but the rough idle and hesitation when acceleration still remains. I had the computer read and the only problem or suggestion that I got, was that the MAP line or port could be clogged. I don't know what this is, but I have the manual for my car, so I'll try to find out about it. If anyone have more info on what this is, please help...thankx in advance
