Thanks for the reply, sorry to hear about your Taco $$$. My truck does not run rough at all, so looking good. Also, I lived in southern Cali where the weather was almost always over 60 degrees, might have helped avert damage.
The only thing I can think of is that it occasionally misses when cranking. It will turn over 4 or so times, almost start, pause for a split second like it's having trouble, and turn over again and roar to life. Not sure if that's a problem, it usually starts on 6 turnovers. I'll be changing my fuel filter soon.
Just bought the JBA headers on
ebay. One question I have for anyone is whether the JBAs are manufactured in the USA and fall under NAFTA so I don't have to pay duty to Canada.
