My truck has been struggling to start in the mornings, especially when it's humid outside. I thought for it needed a tune up, I have 140,000km on it, and never had a garage touch it. I got a garage to tune it up, new plugs, wires, cap, rotor etc. The stupid thing starts better, but sometimes it still takes a while to get it started. When driving it hesitates before it kicks in if I hammer the gas peddle. It use to go real good. I also tried fuel injector cleaner that you put in the gas tank and that didn't do anything. Any other ideas?
Thanks,
Glenn
