truck not running right after tune up
So i proceeded to do a tuneup and ran into a seized spark plug and a mangled heat shield. i ended up breaking the spark plug trying to pull the heat shield out, but i finally got it out with some pb blaster which i am sure some soaked into the cylinder. so after finishing the tuneup i proceeded to start it and the motor shook like it was misfiring really bad and there was smoke coming heavy from the exhaust and alittle from the engine bay. after checking to make sure i didn't cross any wires i figured the pb blaster just had to burn out. after about 5 mins it returned to a somewhat normal idle and no more smoke.
when i went for a test drive it the acceleration is very lumpy and the engine starts to sputter. there didnt seem to be any loss of power though. so i bought new spark plugs thinking one may have a hair line crack as i remember dropping 2 of them. every plug i pulled out was covering in a oily substance and grit which smelled like pb blaster. so after putting the new plugs in it idled and accelerated slightly better. then i decided to try some sea foam which caused it to run at about 90% normal for about 10 mins before it went back to sputtering.
do you believe the pb blaster fouled my spark plugs and possibly ruined my engine? any ideas on what to do to fix it?

it's alittle dark but otherwise looks and smells normal. wasn't alot coming from the engine bay. i think i may have a slight exhaust manifold leak

i'm starting to learn towards it might be out of time

Unless it's jumped a tooth on the timing chain, it's likely not out of time. And your positive you got all the new wires in the right spots on the distributor cap? Something is not right if it just acted up once you did all this.

not yet, i will do it tomorrow along with checking the cap and button

Timing is pretty much fixed. It's all controlled by the PCM, and the distributor has basically nothing to do with it. Just doing wires and plugs isn't going to throw it off, and the timing chain would have to be REALLY bad before it would slip a tooth or so. (in fact, if it was that loose, you would have been having problems before now.....)
Check the plugs, see what they look like. Make sure cam and crank sensor are plugged in good.
