Really at a point where I don't know what to do with my truck.
Truck had latest intercooler TSB done 2 months ago, felt very powerful for a few days after then dropped off and misfire came back.
I put in new SP-528's about 1.5-2 months ago I believe, gapped to .032. Truck again felt very powerful for a couple days...then dropped off again. But misfire wasn't really noticeable.
Been driving on these for like I said 1.5-2 months, several thousand miles. Still feels very lacking in the power dept. Haven't noticed an all out misfire like before but sometimes it seems like it hesitates...like the RPM's don't move up at certain points.
Think I am going to put in the SP-534's soon as I get a chance...however I am turkey hunting the next 2 weekends so may be a couple weeks.
Some say the new I/C is a POS causing lack of power...some say plugs...some say coils. What do I try? How much money do I have to throw at a truck still in powertrain warranty?
I think my next step is the SP-534's and try them a couple thousand miles. Then do I buy aftermarket coils and install? Then I need to make the decision of having the dealer look at it again and trying to lemon, or putting on an aftermarket I/C and tune...cause as soon as I do that they are going to blame everything on that. My biggest concern is with all my issues...adding a tune is going to wreck something.
Just wish it ran like the first day I had it. Thats all I want.
