pinging engine 90 toy pickup 22RE

[Dunzrat72]

i apologize for asking a question when you are looking for answers. I recently bought a 1990 toyota 4x4 with a 22re engine from the bank that was turned in as a repo, the kid dropped it off and figured since he was losing his truck he thought it would be kewl to leave the ignition on, open the hood and pull ALL the lines loose from the intake, EGR, pretty much everything under the hood that wasnt bolted down!!! Amazingly the truck still starts!! runs normal now after changing plugs, wires, rotor and distributor. unfortunately i have NO idea the routing on any of the vacuum lines under the hood. I do have the sticker under the hood and even the Chiltons diaghram but it looks like a big cluster of black where all the lines come together. I am desperately trying to get these hooked up correctly, if you or anyone has a picture, or could take a picture for me, that would be AWESOME!!!!!! the truck runs, and idles correctly, runs smooth but has NO POWER at all, first gear is fine but has hardly any response when accelerating or climbing hills. ???????? Always been a Dodge guy and just picked this up for a hunting rig, any help would be greatly appreciated!! contact me at [email protected]. again, thank you!!

I know this is an old thread, but this solution might help. My 4 runner lives at 9K ft in colorado, and now I am at sea level for the summer. I noticed the same ping mentioned when the engine was under load (stepping on the gas). I went to the Toyota dealer and asked them to adjust the timing properly and the guy told me that on an older truck the timing mechanisms will probably be off. He advised me to just go by ear, which is easy to do, and it worked great (no more ping at all). This would make sense for the earlier post because although the guy did install a new T-chain, maybe something else was worn and was not allowing the properly adjusted timing to function correctly. Here's what the mechanic said..."loosen up that distributor cap so you can move it but its not totally loose (all models are different but this should be easy to do) and move it the other way until it pings real bad (now you know where its NOT supposed to be and he said this shouldn't hurt the engine at all, especially if your not driving it 40K miles like that), then back it up a little bit at a time until its not pinging anymore. In order to do this you need some open road and the ability to stop for adjustments. It took me about 15 minutes and I was able to dial it in, which increase MPG and gave me more power, AND stopped that annoying sound. Once it's dialed in tighten the bolt(s) and your good. REMEMBER...back it up just a little with each twist away from the pinging location and you should be fine. Hope this helps, it sure helped me.
