Took my 2007 dodge Ram 1500 4x4 into Jiffy Lube for an oil change on Christmas Eve and 20min later as soon as service was complete. I hop in my truck start the ignition and my truck begins idling rough and has a shake to it, this has never happend before since owning my truck so this had me very worried. I put into drive and push accelerator and my truck has lost power like it does not want to accelerate i continue to push on gas and i began to go forward with loss of power and check engine light comes on my dash and begins flashing off and on. I pull back into their shop and ask them.what was the problem with my truck since everything was fine prior to me getting oil changed. They proceed to rechange my oil and put diagnostic machine on my truck to read code and it comes back p0300. At this time my truck will.not start so Jiffy Lube has my truck towed to a local Firestone to be diagnosed. Firestone comes back and tells me i need to have my headers removed and resurfaced and that my water pump appears to be leaking as well which i have never noticed any leaks prior to oil.change. im really stuck on this one and really need to get fixed asap

Hopefully you have a repair shop that you deal with frequently and one which you trust. First thing I would be doing is getting it towed out of Firestone to your repair shop. The way I see it one of two things could have happened. Oil change guys did something or some failure coincidentally happened at the worst time for you. The fast lube guys should only have disturbed the oil drain plug and filter...and usually they remove the air filter to check and hopefully sell you a new one. Performing these functions should not have any effect on your symptoms as described. Just throwing this out there...Why did they change the oil a second time? Highly unlikely but did they grab the wrong bulk refill hose and fill your engine with an inappropriate fluid (coolant ?) Instead of engine oil ? I could be way off base with this but.... Get it to a trusted mechanic for proper diagnosis to see if jiffy messed up or it just happened to be a coincidental failure.
