That's all been checked and double checked. Zero leaks on the intake tube.Make sure you didn’t knock the intake tube loose from the throttle body.
Yeah, sorry I needed to go back and read. This is truly a perplexing problem.That's all been checked and double checked. Zero leaks on the intake tube.
It would cause an oil leak.Just thinking out loud now... If the oil pressure sensor wasn't tightened down quite tight enough, could that cause a vacuum leak?
I managed to reset the LTFTs by disconnecting the battery.Some scanners will allow you to reset the LTFTs; that would be something to try. I'm wondering if disconnecting the battery for a few minutes and touching the cable ends together, or turning on the lights to drain any residual power, would reset them.
