The price for 8 right now is $304USD+ tax, so I was considering RCInjectors in Torrance does cleaning service for $200.. but without knowing what leads to this issue it’s hard to say if updating to a newer version of these injectors would even be worth the cost vs cleaning what I already have. I did have a bad coil on that same cylinder which I think lead to the misfire.. correct me if I’m wrong but I think that could cause an injector to stay open and flood it’s cylinder.

It's a common ish direct injection problem. They can get dirty if you use ****ty fuel AND don't have a catch can.

These were mine after 10years of use. ALWAYS use Shell 91 non ethanol fuel and had a catch can since pretty much day 1.

replace them or upgrade to higher flow injectors with a matching tune.

I alternate between Shell 93 and Speedway (Marathon) 93. I don’t have a catch can, should I install one of those while I have the engine apart? If so which one should I buy?

Are the gains worth the additional ~$600?

if you plan on running e85 during fuel price hikes or go supercharged you'll need the higher flow injectors.

These are the original injectors my car left the factory with ~11 years and 126k kms ago.

Probably for the best that i had them changed

Warning!
If finding cheap injectors in Europe.
They are most certanly chinese copies.

Almost impossible to tell the difference by the eye.
