Plenum Pull - Anything Else I should do? - ZR-1 Net Registry Forums

gbmidyear66 · 05-11-2010

Well, I got up the courage this weekend to tackle the plenum (while I waited for the parts for the FX3 system to arrive).

I bought a set of GM "look alike" injectors from FIC, and the Haibeck video. The biggest issue with the pull was getting the cap off the blasted overflow coolant tank (to drain out the coolant) it just did not want to come off. Everything else has gone smoothly so far.

Did a lot of cleaning up under there (using a rag, TSP, solvent and toothbrush), and have now re-installed the rails with the new injectors in. I had 3 primary and 3 secondary injectors with less than 9 ohms, one primary and one seconday had less than 6 ohms. I am hoping I will feel a difference (and the car - when it warms up - won't sound like my TDI any more).

I have re-torqued the IH, the air box bolts, powerd up the fuel pumps and checked for leaks, tested the operation of the secondaries. The coil packs and wires were changed about 6 years (about 10K miles ago) - so did not touch those.

I am now ready to put the plenum back on. Is there anything else I should do or check beforehand? Anything else I should know about re-assembly (mine is a 90)?
