So, I have a 87 GT with a bored 306, mild cam and heads. When I do a cylinder check using an innova 3145 reader it is only showing 6 cylinders. The engine doesn't sound like its running on 6 cylinders. I checked the gap on the plugs and everything is normal. The plug wires look ok. I have checked 3 injectors for resistance and they were all within range. My question is could it be the computer or something else. I thought maybe the salt and pepper shakers in the back but after last look the wires coming out look good. I have a smog delete kit if that helps.
Thank you in advance.
Cheers!
Josh
