I bought one of the SCT performance CHIPS a few years ago but ever since I have had an engine knocking problem between 2-3k when going up hills or towing something. On hots days its worse. temps over 80 degrees. I have ran all types of gas and no improvement. Going through some of the mountain passes here in AZ I just listen wondering if this is the day it blows a hole in the side of the block. I had an old jeep and the same noise blew a hole through the engine wall and shattered a rod and a piston because of bad timing.
Anyways I pulled the CHIP about a year ago, took it to the dealer for a diagnostic and they said it was more than likely my MAF sensor or the K&N filter, suggesting I switch back to the stock airbox. I replaced the MAF sensor and still have the same problem. Now I'm looking to buying an airbox.
When disconnecting the battery does it reflash the ECU back to stock? I think that is were I should start but I'm assuming only a dealer can do that.
That CHIP cost $300, I could barely sell it for $100, and ever since I have had problems!
Any ideas?
Thanks, Jason
