At 1400 1500 rpm there is a random misfire note out of the exhaust but not anywhere else in the rev range. this has been happening for a while now and so i thought i would come here. i have heard (and worked on)cars with dead cylinder misfiring but it wasn't like this or as subtle. Location. queen creek, az. sep 30, 2011. #6. the head design on the 3vze is lacking as far as adequate cooling goes. cylinders #4 and #6 are notorious for burnt exhaust valves. i replaced heads twice with rebuilt ones, only to lose compression on those cylinders very quickly again. A healthy coil should typically have a resistance reading within the range of 0.5 to 2 ohms. for the spark plug, ensure the electrode gap falls between 0.028 to 0.060 inches. any deviation from these values could indicate potential issues causing the cylinder 3 misfire. inspecting cylinder 3 fuel injector.

This was pulled from toyotanation forum. i found this excellent for folks trying to maintain the toyota v6 3vze engine. i bought my 89 v6 4x4 x cab in 1995 at 107k miles and now 14 years and 173k miles later, it's still going strong, so you could get a lot of years of good service out of that. Step 1 – check spark plug wires. they could be worn. worn spark plug wires could cause an engine misfire. if the wire is cracked and the current isn't flowing properly, the spark plug connected to that wire might not spark, which would cause that cylinder to misfire. to inspect the wires, follow each wire from one end to the other.
