Ok 350 tpi I finally got it running an Idling somewhat smooth my question is I'm getting some hesitation when I give it the throttle what could be the problem so far I changed wires, spark plugs an the cts

 

Some more info would be handy.

Is this a fresh install ,
a engine that had problems and was not running
or what.................??????????????????????
Have you checked the codes 1st?

 

Sorry about the whole making a new thread of the same topic something weird happened saying it expired, ok so here's the situation when I first got the car home it was running really rough few ignition wires were cracked causing misfire, no 02 sensor was installed into the heddman headers so I fixed that the cts connector was broke fixed that, the motor has 111,000 on it oil pressure is around 30 psi, temp runs aroumd 190 an is steady no engine light is on at the moment. Starts up fine an idles it's just when I give it the throttle it takes a few seconds to climb up through the rpm's. I've replaced the spark plugs with ac delco r45ts with 10mm Taylor ignition wires. Havent got to change the cap an rotor yet for the dizzy, nor have I checked fuel pressure or checked the fuel filter, I do have a new fuel filter but I have to change acouple of lines fuel lines are starting to rot out pretty bad, alsO along with the brake lines
