'93 4Runner 3.0 Auto Speedomete Goes In and Out Randomly
 

Hey hey. I recently purchased an awesome 1993 4Runner 3v Auto with 153k miles. Its been struggling alot in drive, to which I ran the codes and got 41 (TPS), 52 (Knock Sensor) for the engine and 62 for the trans (bad No. 1 Solenoid). I also took it to a transmission shop for a full diagnosis to which they found the exact same result. What I can't figure out is my speedometer... it is accurate while I am driving 60% of the time and other times I'm driving is it at 0. All of my other gages fully work 100% of the time.... Any ideas what this could be? Could it relate to any of those codes?

do you have any photos to share ?
