Client brought their Na1 to me for some work. Inspect engine mechanical timing- found to be one tooth off. Performed cylinder leakage test to validate engine health and combustion chambers are sealed up. Then decided to perform the timing belt
Package which includes the belt, the tensioner, water pump, vc gaskets, oil filter housing gaskets. Also ordered up some new spark plugs and gapped them to spec and installed those. Then did a valve lash adjustment. The car is supercharged; so working around that was a new challenge. It’s been a while since I’ve worked on one of these so I was rusty; but got everything done in a timely fashion nonetheless. Lastly, I found that the engine performance was inconsistent and randomly the engine would begin to misfire. I found that the injector jumper adapters were causing high resistance— so we modified the factory harness by splicing in the appropriate injector harness pigtails. Much better. This thing rips.
