OK, as I thought the air cleaner was OK, changed it anyway though. I plan to pull the injectors and have them tested. My question is do the injectors just unscrew? If so are they clockwise or counter? I will do a compression test while I have them out. With 195K miles on it what should I expect in the way of readings. I know the maintenance done on the car since I have had it, but not to clear on the P.O. Any insight into the injector removal (tricks or problems) would helpful.

Greetings,

If you pull off while twisting slightly the injector bleed lines the injectors unthread counter clockwise using a 27mm socket. Please mind to be careful not to apply sideward pressure to the socket to prevent benting or knocking off one of the bleed nipples.
Insure to remove and replace the injector metal seals between the injector and the head.

Hi

I don't have a lot of experience on injectors removal, changed mine for the first time a couple of weeks ago. But I can say that they unscrew in the normal way, i.e. counter clockwise. Care should be take not to drop any dirt in the prechambers (clean the space around the injectors with compressed air before removing). It is recommended to renew the seal washers under the injectors ; check the orientation, flat side toward injector. Clean the contact area of the prechamber with the injector seal. Oil the treads (or use anti seize) before retorquing the injectors and do it in a single shot. Fuel lines don't need to be over tightened : just check for leaks. Didn't have to bleed the fuel lines on my car, but I saw somewhere that it could be done : just loose the fuel line at the injector and retight (watch for the splash).
