This may be, I am not here to get into a pissing contest with anyone over it. I am just looking to help a friend. That being said, you may wish to contact the writers of Mitchel on Demand, they have it listed as a backfire through intake.

There may be a vacuum leak, (internal or external) with the intake gasket, or possibly a leak in the air inlet between the MAF and the throttle body. Either scenario will cause a lean condition which can cause induction. Depending on where and how large the leak is, it may or may not set a DTC. The OBDII system does not monitor secondary ignition, fuel delivery, or base engine mechanical problems.

I do not know where it is happening since the one time it has happened in my presence I was inside the cab and did not hear it, just felt the hesitation. He told me it backfired. The car is not here and he has not brought it over today, yet. When it was here I checked compression, plugs, wires, cap, rotor, fuel pressure, etc. I did find the vac line to the vac ball on the hood was deteriorated off and just laying there, so I cut it down an inch or so to where it was still good and re-attached it. If he shows up today I will just replace the lines, or have him replace them and see if that helps any. Thanks for the heads up on this.
For either/both of you, or anyone else who may have input.
The shop I am borrowing the MT2500 scan tool from has just bought a Modus, since support is about to be dropped for the 2500. He offered the 2500 to me for $550 with all he has for it. What would I be looking for as far as cartridges, keys and software version? A brief history on myself is I have not worked for a shop for 18 years and have not been ASE certified for 16. I typically do nothing major other then help out people who ask. The newest car I have touched recently is a 2005, and that was just a wheel bearing. Is the brick worth it? I have seen the Solus going for as low as $850. Would it be better to scrape up the extra cash and hold off for a deal like this? just looking for opinions. Thanks to all who reply.
