i'v got an 1987 ranger with a 2.3 and 177,000 miles on it. the problem is: it always blows white smoke when it's under like 70 degrees, and when it's cold and i go to start it sometimes it will shudder and die within 1-2 seconds then i can get it to fire up right after that. also when i'm lead footed for a while then go back to normal driving it really boggs down. could this just be means for a tune up or something more serious? one last thing, how fast do oil pumps go out? cause when i go up steep hills there is a clicking noise, but my oil is full. somebody said that it could just be going bad.
