I've got a brand new 22re from 22re performance in my truck as of July last year. lately I had some problems with some wires shorting out and caused the truck to not be able to start and therefore removed a bunch of excess wires that were from previous owners mods and the problem disappeared. Now once I have removed a bunch of those random wires I am having a sputtering slow acceleration in 1st and 2nd gear. When I accelerate quickly it doesn't happen and it runs fine at idle. I had a loose injector connector but I replaced that and it didn't solve the problem and I have no idea what It could be. Any ideas?
