Hi, I bought my truck on 12/12/12 and I absolutely love it. However, it has been giving me some problems lately. First the carb quit on me and blew every seal it could and basically destroyed itself so I got a new one and slapped it on there. its the exact same thing its the original Holley 2280. it has always acted weird but now its really bad. when you start it and free rev it, it sounds like its pulling the world behind it! its just bogging itself out and wants to stall like its not getting enough fuel or way too much air like a bad vacuum leak. But, I'm also leaning towards stuck torque converter (its a lock up and its acting like its stuck locked in) or tranny issues because its doing it in park and neutral also. its the 727 original tranny if that helps. Could it also be a stuck EGR valve? If you give it more than like 1/6 of the throttle is when it starts. It only does it intermittently so its hard to get it to do it in front of a technician. I'm trying to give as much info as I can so any help is appreciated. Its my daily driver and I need to fix it asap!
thank you,

 

sounds like a plugged exhaust, the crossover pipes were 2 layer and sometimes the inner layer would collapse or if the truck has a catalytic converter that could be plugged, drop the e the manifolds and run it and see how it is.

 

It cant be that since its straight piped from the manifolds back

 

but thanks anyway

 

ok here's an update: new primary ignition coil, cap, rotor, wires, plugs, fuel pump, fuel filter, fuel lines, checked all the vacuum lines but no issus there... WHATS LEFT!!!! this is really bugging me now

 

I have concluded that my carb is not adjusted properly, and my timing is way off. I did some research and Chrysler didn't do a very good job with making the timing marks on the balancer in the correct spot. I had to use a piston stop that I made from an old spark plug and made my own marks on the balancer with soapstone. it runs much more smoothly and actually has power now. The carb still needs adjusted I just havnt had the time to pull it off and tear it apart to fix the issue.
