What was the "solenoid code"? P0017 means timing chain, not valve.

It was code "p0011" for the intake side solenoid. Decided to do both.

A bad chain is more likely to cause fuel pressure problems.

Best to do both at the same time, the other one will go as soon as one is fixed. I know!

P0089 means the hpfp needs looking at or a bad injector or the intake cam is off. It means that the computer can't adjust enough to get the optimum pressure. The computer is aking for an adjustment of + or - 363 PSI.

I just recently had p0087 and p0089. It turned out to be a bad injector, dumping fuel into the cylinder. Engine reduced power, wouldn't drive at all. I was on vacation, had to take it to a shop instead of fixing it myself. $1,250... moral of the story, fix it now, before it leaves you stranded.

It came on once when the p0011 was on, then the car couldn't find an idle speed it was happy with. I cleared both after I fixed the actuator solenoids and have driven about 60miles today without it popping back up. The minute it comes back, I'll take it to get looked at. Thanks for the tip!

Since the shop needed the injector right away, they had to source from a local dealership, it cost twice as much as Amazon.

The intake manifold has to come off, and special procedures to replace the high pressure, direct injector, so there is quite a bit of labor in the job.

Update: I have since put near 1000 miles on the SS, after changing the solenoids. No codes, no fuel troubles. I'm pretty sure it wasn't happy becasue the solenoids had caused a very erratic and violent idle, and since the camshaft dives the front fuel pump, it was getting vastly varying pressures. Now to buy those grommets, so it doesn't sound like I have a small woodpecker in my engine bay. Just wished I had a decent dealer closer to my college, the wait time on those things sucks.

Please help me understand the right way to put new grommets ("insulators") on. Mine have long since rotted away so I don't know how they should look.

1. The insulator has a smaller and bigger end - which way is up?
2. For new insulator installation, should it go on the airbox first, and then force the whole assembly over the posts, or grommet on post first, then try to push the airbox hole over the grommet?

Thanks, don't want to break the airbox just because I'm replacing a $6 part

A little lithium grease, push the small end into the airbox, then push the airbox onto the studs. I never bothered to put the clips back on.
