Installation is in a confined area on my truck. Not sure if there is any thing or not but a week later my transmission cooked/ grenade itself while I was just crusing down the road at 75 mph. So now I have to put a transmission in my truck going to be about a week of staying after work and remove and installing a $1,600 transmission. Btw glad right now I work for a towing and automotive repair shop.

After following directions(to the letter)I started the truck and the C,E.L. went out and the engine sounded fine. Then,I installed the new exhaust system(Magnaflow Catback)and,K&N cold air intake. Now,the engine runs rough(no power),sounds like ignition leads were crossed(firing on the wrong cylinders). I don't know what to try ,next. I guess I will have to take it to a garage I know and trust. Any suggestions would be welcome.
