I just changed my spark plugs today, it's something I've never done by myself. Felt like it went off as planned, took em all out and put the new ones in. Then I took a little drive and the truck starts right up like it always did but I feel what I can only describe as a sort of lagging or surging when I'm accelerating from a stop. While I'm driving it feels fine I don't feel anything that seems like misfiring or anything.
There also is a sort of bump thats pretty regular when I'm sitting idling, seems like it might be spark knock, but I'm not really sure what that feels like. There also is a slight noise when i'm idling when it gives the little bump. I changed the plugs and wires, I routed all the wires as they were, could it be the wires causing the knock? I saw a tsb about how wire routing position could cause light spark knock.
Any help would be greatly appreciated

 

Yes, improperly routed wires can cause spark knock, but not at idle.
What you are experiancing at idle is more likely "cross talk" aka, electrical interference (?)
Re-route the wires per the TSB and see if it goes away.
Pull your TB and clean it if you haven't already.

 

Okay thanks, I was wondering why the tsb doesnt specify how to route the number 1 wire, I guess it isn't a big deal but I will try that tomorrow and see if it helps

 

I don't remember which wires are not allowed to touch each other.
There are two specific wires. no.7 and another one. I just don't remember which.
You used plastic conduit tubing, right?

 

I bought Auotlite plugs and wires, it was a set, came with convo on the plugs

 

And when your done screwing around and wasting money, fix the blown plenum, replace or gut your cat and install a new o2 sensor.

 

I love wasting money on my truck, pretty much my only motivation for living, I've only got 75K on it, I did the plugs because I wanted to, Besides that I"m pretty positive the truck is fine, if the only sign of a blown plenum is oil pooling in the bottom of the tb then I think I'm good

 

Did you gap the spark plugs correctly ?

 

i am willing to bet that a plug wire is not fully connected at the plug or at the distributor.

It will cause a miss which will give every symptom that you stated. Check to see if all the wires are fully set on the plugs and the distributor.

 

#5 & #7 are the two that are finicky.
