98gs3

I am interested, what do you have in mind? I don't think it's an injector myself.

anyone knows a part number on the fuel injector?

I can't tell you guys the exact mileage on my car, 1.5 years ago my odometer just stoped and showing 79,xxx mileage for the past 1.5 years. So I am sure I am pretty close to 100K. Is doing spark plugs sufficient, or is there wires/coils involved as well? Any recommendation where to get a cheap fuel injector just in case?

I nevery replaced the plugs/wires, is it hard (specifically for cylinder 5)? AutoZone told me the wire set comes with only 3 wires, is that normal? What about the coils? Is that something I can check myself?

Is it an injector for sure, should I order one? The codes were: random cyl misfire, cyl 5 misfire, and random cyl misfire again.

Hey guys, I have a 98 GS300 with over 100K, I got a check engine light, Random cylinder misfire and cylinder 5 misfire. The car runs rough, shakes when accelerating, sometimes with a bit more acceleration it will backfire, real loud noise. 3 years ago Lexus replaced a bad fuel injector. Any suggestions what could be wrong now?
