97 k1500 p0300

Hi so I replaced my distributor today after having a p1345 code and it took the p1345 code away, now it has a p0300 code and is running worse than before like it has almost no acceleration. I set the cam retard to 0 with a scan tool, any ideas? I forgot to mention that the truck was running great prior to replacing the distributor and there was no p0300 code. I had a buddy help me set the cam retard and he had his scanner under the hood adjusting the distributor while it was idling,now I read somewhere else that you have to have it at 1100-1200rpm while setting it cuz it can’t be set at idle is that correct?

That is correct. 1000-1200 rpm’s. I shoot for 1100.

Okay would it being offset a little cause my truck to be super doggy? Like half throttle it barely accelerates up to 60 like it is out of time or something. It wasn’t doing this before I replaced the distributor.

being offset a little

I don’t know how much it’s off. I’d just reset it properly, good chance it will correct issue. How are your plugs?
Which distributor brand you install?

Did the distributor come with a new cap? If so, try swapping on the old cap.

Sounds like you are speculating about the cam retard setting you did at idle instead of the recommended 1000 to 1200 rpm. Reset at the specified time and you will be enlightened.
I can only assume, you did not say, that the new distributor came with cap and rotor. Hope it is a good quality distributor, like @Caman96 was asking about. What condition are the plugs in. Pics if you can, of plugs and old cap/rotor.

So between new parts installed and the work you did something changed.

Yes like it is out of time or something and now it’s giving p0300, it wasn’t doing any of this before just a p1345 but that code is gone now.

Yes it did. I’ll try that

Yeah my buddy set the cam retard under the hood with his scanner under there with him, when he was doing it he was just snapping the throttle every time he adjusted the distributor. I don’t know if that is the issue since you’re supposed to raise the rpm when doin it? The plugs and wires were just replaced as well they all look good upon removal now.
