Can't win!
Here is the deal.I installed an Optima battery about a year ago..No problems. Later disconnect the battery to do some work. After hooking battery back up I started having idle problem .Soon I started hearing a knocking in the engine. Took it to ford dealer. They had the truck for 2 weeks ripping it down to replace cam, lifters, etc. When I got truck back, the noise was gone. But I still have rough idle and vibrations at 1100 and 1800 rpms.
I took back to dealer.
They checked everything from compression leaks to up date PCM.etc said truck engine is 100%.. I still have same problems.And prior to the work they did, I did not have the vibration problem. It may be a long shot, but after disconnecting battery you should go through a prosess of letting engine warm up operating temp, then run the A/C for at least 1 minute. Then drive 10 miles.
Could that be the problem? Is it that important?
