Misfire help

[Jroc860]

You need to do a leak down test u may have a burnt valve. U ever adjust the valves.

Yea we did a valve adjustment need to try the leak down test thanks. Any other suggestions

Is the ecu registering which cylinder is misfiring?

[hondaek]

Yea it has a cel for random misfire. We don't have shop air to do a leak test so were kinda stuck

[Mr Layy]

Which harness are u using? What motor is in there? Check the timing?

Ok ive read u changed wires but where they new?

[hondaek]

Yea changed new wires plugs rebuilt dizzy used injectors clean iac changed PVC. The only thing left to do is check timing I guess

[hondaek]

Also did comp test and all cylinders are good even the misfiring one and using stock harness with stock engine I assume, he just bought the car. Wud that matter?

[Mr Layy]

Just wanted to know, but with the car started, try removing each injector one at time, and see if that makes it run... Whichever is bad, there might be a wire issue.

[hondaek]

Tried that. Injector was bad( one) replaced it and still the misfire. If we remove the ignition wire on the misfires cylinder it makes no difference in the way it runs

Are your spark plug wires touching eachother anywhere? They can ground out through the wires and cause a miss fire

[hondaek]

They were touching and we separated them after and still the misfire. Wud we need to change the wires cuz they were touching b4?
