Cylinder 1misfire...fixed

Hi Everybody...long time lurker...

I have Four Gen 2 Priuses all 200k+ miles... used to have five...first one lasted 306k miles... bought it brand new 0 miles in 07

I've gotten lots of information from this forum over the years so I thought I'd give something back...

I had a check engine light with a code of cylinder 1 misfire ....couldn't get rid of it... change the plugs.... and the coils ...went through about four bottles of fuel injector cleaner .....nothing would get rid of it...

and I couldn't get a smog check because in SoCal and the check engine light was still lit

New fuel injectors are $100 a piece at O'Reilly and $200 a piece from the dealer...

The O'Reilly's guy suggested... why don't you just clean them.. good idea!

Took the car home... only took about 5 minutes to pull them out.. got to be really careful and have a vacuum cleaner with a small hose ready to suck out any crap dust debris before it drops into the cylinder

They were REALLY dirty!

Scraped them with some wooden popsicle sticks split in half... and blasted it with throttle body cleaner and shop rags....And they look good as new

Installed them back in the car...turned it on and the check engine light went away all by itself.. drove the car 200+ miles and no problems.... feels like a RACINGPrius now!... checked it with OBD II...itll pass smog check no problem

 

Yup I cleaned all 4 injectors...

Bought 2 sets of replacement Orings because thats all they had...but the stock ones looked good so decided to leave them in...hopefully not leaking but will check later

Is THAT how they work!?...hit it with 12 volts and blast it with compressed air...See!...thanks again!...I was almost certain I had jammed some gunk into the little holes and wasn't sure how to clear them out...ok will try that too!...awesome
