Just installed new engine and drove car a couple of miles when CEL came on and car in limp mode, I smelled fuel shorty after getting car started and could not find the source until looking closer and then I seen fuel coming out from under intake manifold so I am guessing injector seals and O-rings which I did not replace or know to replace so I am thinking this leak is the reason for the P0089 code. When I had the intake off during engine swap I sprayed carb cleaner in the intake to clean it up, I figure I screwed up or dirtied up a map sensor and maybe this is the P236 code and maybe the cause of limp mode. I have new seals and O-rings and tool ordered. Do I put the injectors in the rail before mounting to head or injectors in the head and mount fuel rail to it? Also can the MAP's be cleaned and tested?

 

The injectors go in the rail first. You'll want to alternate bolts to keep the injectors straight as they're going into the head. The leak could be from the high pressure fuel pipe also. The fittings are tightened to 21 or 22 ft. lbs.

 

Just get a whole new fuel rain and injectors pre installed. It's easier.

 

It's not hard. Not worth getting an entire fuel rail and injectors for.

 

The high pressure pipe was not leaking. Is there a way to check or clean the MAP sensors?

 

I squirted some maf cleaner inside mine with no harm done. I tested mine using a hand-pump vacuum and watching the readings on my obdii software compared to the pump's gauge.

 

I think I found the source of the P0089 and maybe part of the P0236, some un-soldered MAP sensors.

 

Got seals changed, cleaned map sensors, cleared codes. Now no codes but also no boost. Not sure if its in limp mode or not but has no power, struggles to run 60.

 

No boost means limp mode. Check for vacuum and boost leaks.

 

My helper left a shop towel in turbo inlet, no problems now

 

Things happen. Easy to miss

 

So you're all swapped, running fine!?

COOL!

 

Yes everything seems to be fine, have about 200 miles on it so far.
