My 94 Q45 injector #6's OHM reading was not within 10-14 recommended number.

My question is:Should I chage it with a working injector when I do my under plenum job? ORIs it worth giving it a try and doing a BG system flush by a shop and see if that'll get the injector unclogged?

A BG rail flush (not an intake fogging) won't hurt, but may not cure.

It may well help your other injectors even if it doesn't cure the bad one, which you will replace with a new one anyway if it remians bad.

The resistance indicates the condition of the injector coil. BG can't help that - only cleans the injector. At least move that one to the front so you can get easily at it later.

True, but a clogged or dirty injector will require a higher curent draw and thus indicate more resistance.

Whether the pintle moves slower due to deposit friction is pretty inmaterial.The injector resistance determines the current peak.

Sorry guys. You missed it. Tech caught Brian in a weak moment. He will have figured out the error in his ways and be back to his normal self by the time you read this post.

He should be hooked up to a BG transmission fluid exchange machine and get the full 14 quarts run through his brain,but only after injesting the BG chemical cleaner and doing jumping jacks for 15-20 minutes first to loosen the sludge and varnish from his brain!.....
