Rough start/acceleration after.....
Hey guys what's up ? Well here is what I've done , Friday I put 8oz of seam foam in my oil , yesterday I put in the intake hose and went through the steps and it still drove fine after the smoke show , then I installed my new Taylor shorties ,I tried to start it and it took awhile for it to start, once driving I did a quick WOT run and it started chugging like it was running out of fuel . I don't know what could be causing this . After the shorties should I have disconnected the battery for a reset ? Any help would be greatly appreciated !

Thanks, Chris

Try resetting battery, are all wires hooked up correctly? Make sure hose that you disconnected to put seafoam in is reconnected, also when I seafoamed mine the spark plugs became found so I changed them out.

Yeah wires only go on one way with the shorty wire setup , reset battery now and take for a blast down the highway and see what happens lol

All else fails I will check the plugs !

That's the map sender or manifold absolute pressure sensor the one I replaced on my jeep cam with new screws

Yeah it is the map sensor that I bought but the one on my jeep doesn't look like that
