So I have a 1994 Chevy K1500 that has been a great truck but is now having some issues that worry me. It recently got cold here in Nevada and since then my truck has been idling really rough and has lost a good bit of power. Along with that it now ticks really loud when under a load. It does it around 40-50mph at about 2,000 rpm but never when in park or neutral no matter how much I rev it. I just did an oil change on it and followed my mechanics advice on using a heavier weight oil (10W-30) as opposed to the usual 5W-30 that the oil cap says. I thought it was the valves ticking but everything I've read suggests that if that was the cause it would be constant and not just when I'm driving. The pattern seems to stay exactly in line with the rpms though so I'm at a loss. Anybody have an idea of what it could be and how much it's going to cost? Thank you.
have the same problem?
