Hey all,
Not a good night. Motor started sputtering when reaching 3000 rpm. Half-way though a tank of gas. Idles fine. No odd noises. Sputters under acceleration and in park. Google has not been any help. Thoughts? Any help would be greatly appreciated. -------------------- '99 Triple Black GT Convertible

Just picked up the broken Celi from the dealer. $120 for a diag.
As I understand it, turns out a bad O2 sensor (been bad for awhile) was causing the motor to run too rich (I was only getting 20 mpg) and the unburned gasses melted the Catalytic Converters. Too much exhaust attempting to go through the confines of the melted converter is causing the sputter. That is the story from my local Toyota dealer. From what I have read this is common. Cost for 3.5 hours (!) labor, the exhaust manifold w/ front converter, rear converter, 2 sensors and 4 gaskets? $1500 installed. Wha-wha-what?! As a reference, the cost of parts from Advance? $500. These are for direct fit parts, not universal. I have a high-end muscle-car co-worker whose son is a mechanic at a local dealer as may be interested in looking at it. Looks like these are bolt-on parts. Can anyone confirm? -------------------- '99 Triple Black GT Convertible
