noticed my engine was shaking alot at idle... so i took a led point thing and connected 1 end ot the battery and stabbed each wire on the cap and when i stab cyl 2 the engine stops shaking... so 2 is not firing properly...

i changed the wire... stilll missing... its a random miss... possibly the plug is fouled but how would it get fouled?

bad ring?
injector is spraying wrong?

little help been a problem for quite some time now!

could be a weak valve spring..valve hanging up in guide, bad plug ..leaking valve..ect ect...start with the easy then get more technical

If the plug is fouled the injector might be leaking. Put a stethoscope on that injectter and see if you here anythig different.Gothe other injectors and seeif it sounds different from the others that could be the prob. hope this helps

uhh checked the plug it was a light grey color...

somtimes the car feels like all 8 cylenders are missing mostly when its cold it happens

but at idle 2 is not firing properly

i took the boot off the cap and was getting arc

im lost here...

im gonna run a compression test on them all, hopefully its not the case it has low compressions
