Running at 45-50 mph in third gear on Interstate 30 is not fun. :( Found some affordable replacements at carparts.com and my new indie did a great job of installing them, including cleaning the carbon out of the secondary air injection tubes.
Runs like there's a new engine under the hood now, and the transmission upshifts like it's supposed to again as well. No more SES light either. :D

That's terrible -- be on the watch for engine problems now though. When catalysts break, the engine can suck them back in when there is reversion. Usually this only happens on pre-cats which are right next to the manifold, but any metallic dust in the exhaust is always a risk. Especially if you drove on it.
I test drove an Xterra once which had this problem, and felt like it had about 15 horsepower. Check engine light was on and the car was completely gutless, and the owner said it had been like that since he bought it. He was trying to sell it and completely believed I was trying to swindle him, even though I flat out told him I wasn't going to make him an offer because the engine was probably toast. |
