Just can't seem to get the rail tightened down evenly enough to get them all to seal. :(

Use a small amount of oil or grease. SMALL on the o-ring nearest the tips. Make sure nothing is pinched in between. Apply firm pressure on each one, facing the engine right to left with your thumb on the head of the injector.

If that doesn't work, send me a PM via the link below my post "PM", and I'll see if I can get out your way in the next day or two after work.

You must have beer.

FWIW

Totally agree with that...

And Also agree with Bill B....

A little vaseline or oil on the Injector O-Rings will save you a lot of trouble... But you will have to guide the injectors into place and then once you are sure none of the O-Rings will hang up, give the fuel rail a gentle push down untill you feel the injectors seat, then install the mounting bolts...

I'd suggest against grease. In case it'* not o ring friendly. Break out the vaseline...mechanics all over have it in their boxes..and now you know why.

I like to apply a light oil to the injectors the night before you remove them.
This makes the o-rings a little softer and plyable. Easier to work with.

Okeedokie! The injectors are now set - no more gas leaking. Finally!

Thank you, thank you, thank you - again!

However - though it'* running smooth and no more noises either - it is shifting slightly late, and isn't kicking into overdrive or passing gear.

Check your TPS (throttle position sensor). It'll do that. All of that. I bet your cruise control doesn't work either. You would have disconnected it to remove the throttle body.

Also give it a couple hundred miles and change the oil and filter again to make sure you get out all of the contaminents..
