2009 w/ 140k. Same repairs as above, minus throttle body, but add: PCM, ECM, fuel injector (stuck open and fried Cat), fuel rail, Bank 1 Cat, 3 oxygen sensors, wheel speed sensor, 3 new window switches, Evap valve, new speaker, new rear wiper arm, new liftgate switch. Probably more but cannot remember offhand. This has been one of those vehicles that is great when running, but a nightmare otherwise. Looking back, these Lambdas were originally engineered and cost-speced in the mid 2000's and appear that every possible cost saving (read cheapening) measure was taken with suppliers and assembly, across the board. GM knows well, all the problems with some of these systems. A goodwill gesture would have been bumper-bumper for 100k and full power train coverage for 200k or similar, given the known problems. I've spent more repairing non-standard wear items on this vehicle than all of my other vehicles combined.electbc said:I have over 175,000, Water pump, Power steering pump, 3-5-R waveplate transmission rebuild, Throttle Body, 1 Wheel Bearing, Both Struts and rear Shocks. All on my dime. Still love the truck.
CEL with P0430 Catalyst System Efficiency Below Threshold (Bank 2). When the light first came on, I reset it a couple of times and there were varying degrees of time between when it would appear again, until finally, it stayed on. Since our next emissions inspection was not for almost a year, I waited until the month it was due to deal with it. Lots of things can throw this code (including leaky exhaust or bad O2 sensor), however, we had just gone through a stuck injector on that bank that dumped raw gas into the exhaust and that almost always fries a cat so I just guessed. Bought OEM one online at discount and had dealer install.topdollar69 said:vwtodd,
when you had the bad cat, what were the symptoms?
