Had codes 300 & 307.changed plugs,cap,rotor,coil.wires are ac delco and only year old. No help. Then found out it had bad injector. Had the spider type. so put in the new mfi injector. This helped a bunch. But still has just a very little stumble at idle and giving it gas. 161000 miles.I think its just old and things worn out!

Changed plugs cap & rotor.Number 7 plug all black and foil looking.Still has stumble and codes 300 & 307 came wright back. notice orange fire not blue or white. Changed coil.Same thing no change.The owner called a another shop.And he said intake pressure valve or burn't valve. Witch I was getting ready to do compression check.The new plug in number 7 was still white. And got 120 psi. All the rest of the plugs was showing signs of firing and 160 to 180 psi. I'm thinking burn't valve. Also smell gas while its running and lots of water out tail pipe and from muffler.Maybe cracked head or gasket

Number 7 cylinder plug was real black and burnt. rest were tan. And the cap and rotor was real corroded. Changed plugs cap and rotor. Cleared computer. Still got same miss and check engine light came back on with same codes. I can't believe the one injector for all 8 cylinders. Would make just number 7 misfire. And the plug wires were new last year. AC delco. Maybe a compression check on that cylinder.
