Code Reader Says V6 but it's a V8. Defective or user error?
I'm trying to decide whether I should return the Inova code reader I bought for my '95 F250. Pretty sure I followed all the instructions. But the code reader said 6 cylinders when the motor is clearly a 351w V8. I did warm the truck up first. Anything I might have done wrong? Thanks.

Clean the pins in the data link connector then re-run the KOER tests. If it still reads out the truck has a 6 cylinder engine then remove the computer, open it up and look for signs of leaking capacitors.
Also note the part numbers on the computer case. We can help decode what it was designed for. Perhaps someone swapped in a 6 cylinder PCM for some odd reason.

thats what I mean, it shows as a 6 cylinder instead of an 8, OP look at the engine, how many plug wires are on the driver side of the motor? if theres 4 u know the code reader is messed up, if theres 3 your truck has had an engine swap.
Also how did u decode the VIN? I have found some sites before that mess it up

Ok, here's an update. I sprayed some electrical contact cleaner on everything and re-ran the tests. Now it tells me I have 8 cylinders. Something must have been dirty or not connected tightly because I get more trouble codes now than I did last time too. Thanks, guys.
Sorry for the confusion about the V6. The code reader doesn't say "V". It just gives a number of cylinders and I just stuck a V in front of it because I have V on the brain...V-8 truck, V-twin Harley...all I have are V's!
