Well Im not sure weather you will get this but I have a 2004 Sahara and it is also on GAS. Last week while turning a corner the Conrod failed and went through the side of the engine also. Toyota blame it on the gas as well due to the fact that while on gas the ecu does not control overevving and so they effectively have blamed me for overreving the vehicle while going around a corner with a caravan on the back while in drive....what a crock !
