Hey everyone, just recently swapped a motor into my truck as the old one was toast. With that being said the used motor had around the same mileage. So after getting it swapped in and hooking everything up i went to start it. It made alot of racket for the first few minutes tapping and what almost sounded like knocking. so after it warmed up everything went away and it ran smooth and i haven't heard those noises again even on cold start up. Now after bleeding the cooling system and taking it for a drive i'm getting this awful pinging at just about any throttle input. And to make things worse when taking off from a stop i get this knocking when i start to let the clutch out and put a load on the engine. It only knocking when taking off, when accelerating or cruising i don't hear anything. If i rev the engine off of idle slowly i can hear the knock faintly and it appears to be coming from the top end. So with me being new to these rangers i was hoping someone could give me some insight as to whats going on with this truck. I sent the better half of the morning chasing down vacuum leaks and think i pretty much got them all sealed. The truck did pop one CEL code and it was for the Idle Air Control Valve. said it was malfunctioning and i can believe it, in between every shift the revs shoot up and hang until you let the clutch back out. So if anyone has any ideas on what to try next i would greatly appreciate it. Until i get these issues resolved i cant take it for a smog test to get it registered.
