Crazy hesitation and wild idle

Bare in mind the car has 120K on the factory plugs and wires. Twice it has thrown a SES Code. One time it registered EGR another multiple misfire. When you get over 3K RPM and floor it NOTHING happens it just yells with no pull. Like it's stuck, then sometimes it doesn't want to run and it will idle like shi* then fix itself.

I just bought plugs,wires, Racetronix fuel pump just gotta install them. Replaced the fuel filter, ran injector cleaner but no worries I WILL have them blasted. Not a big believer in injector cleaner without pressure behind it.


With my luck it will end up being the opti spark but boy I sure hope not. If it wasn't for being able to cut an access cover for the fuel pump I would have pulled my hair out.

Replacing plugs and wires after all that mileage is a start

I think you will see better performance with the stuff you bought installed. The plugs and wires are a PITA and you'll need a lift and visit a site here on technique --else job that part out.
