There is a company in cali that can clean and balance the injectors for like $100 for all 4. Mine are like brand new after the work they did. RC engineering -- ph # is 310-320-2277 ... Good thing I keep all my receipts

 

ok i checked i only have 2 injectors unlike the five series so i am stumped as to what to do there are no secondary injectors please help as for the 6pi the 5th and 6th ports are not opening . actuators need replacement but have no idea how help please

 

what model has only 2 injectors ???

 

compression test resulted in 115 psi per rotor . but i only see two injectors are there two more behind/under intake????

 

Yes. The primary fuel rail and injectors are bolted to the engine block itself, underneath the intake manifold.

 

sweet so that means the two i saw are the secondary injectors ???? right they are located directly above the actuators for aux 6pi correct?

 

correct.

 

thx i appreciate all of your guys' help . the compression is fine so i am gonna procede with cleaning the actuators =]. now say if i clean the actuators and they still dont open where may i purchase new ones thanks ?

 

hey - are you throwing any codes / is your check engine light on?

 

the codes come on and off usually when i drive at a constant speed why do you ask ?

 

Here's a simple question, is your cat clogged?

 

 

i no longer have a cat haha so no =) why is there anything else ?

 

If its doing that when your driving it may be grounds and electrical.

 

Check the tps

injectors don't cost 250.00 a piece. whoever said that doesn't know where to look obviously. You can get all 4 injectors for 200-300 dollars. You don't have to buy them at autozone.

The vacuum diagrams for the S5 are wrong in the FSM just so you know.

sound to me the 6pi or vdi isn't working. Just like when I bought my car. If you are climbing a hill do you have to put it in 2nd or 3rd just to keep speed? )on a freeway hill) if so the 6pi and vdi isn't working.

I can walk you through what to check on vacuum hoses over the phone if you want. pm me your number and a good time to call. I'll call asap. I'm changing my diff right now or id have you call me. well not right now but in like 5 minutes after the exhaust cools down. Probably nobody will know what to check on the vacuum stuff since nobody answered me when I asked months ago.

Your going to need a hand vacuum pump like a mighty vac from autozone to check some of the stuff to make it easier anyways.

Did you recently take the airpump off? or is the airpump belt broken? because that will do it as well.
