My fiance and her 15 year old son own this truck. It has 29,353 original miles on it and has the 5.7L vortec in it. It originally was my fiance's grandfather's truck and basically is was given to the 15 year old son.
The other day her son got the truck stuck in the field. He was with two of his friends and was told to leave the truck alone and his older brother was going to get another truck to get it out. Instead of listening, they ended up getting the truck out but now the engine is missing in cylinders 2 & 8.
Supposedly one of the friends got in the truck and revved the engine up to redline to get it out and who knows how many times this was done.
The plugs, wires, cap and rotor were all replaced about 2,000 miles ago. I pulled the plugs in those cylinders and they look fine with no obvious cracks or damage to the tips. I pulled the cap off and all of the contacts look fine as does the rotor tip.
I pulled the valve cover on that side to see if anything looked abnormal but every thing looked fine.
My fiance's father is a backyard mechanic and did some research and said he found information that states that if you over rev this engine, it will mess up the fuel injectors in the spider and says that we need to replace the fuel injection spider.
My question is, what other tests do we need to do to figure out why we have these misfires and has anyone else heard that over revving the engine will cause a fuel injection problem on this type of fuel system? Thanks.
