Yeah, its lame. But I thought some might enjoy seing my wee little NA barfing some fire due to an out of adjustment TPS. The problem will soon be resolved when the car gets a new tranny and is back on the road.

Mods: S4 NA block and intake manifolds, Large streetport, RP race pipe (just eliminates cats and adds a presilencer), Borla cat-back, stock exhaust manifold, no emissions equip, and other random stuff like a cone filter.

This is mainly just a visual aid to show how something like the tps can throw things out of wack. The car ran fine at the time minus lower fuel economy and bucking on decel. Im pretty sure this is not normal with a stock fuel system and ECU.

Heres the vid:

uhh, they all throw flames after cats are gone. A TPS will make is sputter a lot more. But yes, the stock ECU programming does make it run rich to avoid the chance of running lean.

 

True, but the TPS is telling the ECU the throttle is at WOT (or at least not closed throttle) at all times.
Its really prominant when the engine is still going though the cold-enrichment - pops and farts at decel over 2k
