Cruising around last night in my 93tt, I suddenly developed a miss, which got increasingly worse. Oil pressure was still good so I figured it was fuel related.

Pulled over and popped the hood. By this point it wad running fine again. But I found if I pushed on or lightly wiggled the injector plug, I could make it miss. This was possible on 2 of the 6.

So I see these plugs for sale on sites like z1, so I assume it's a common problem. Do I go ahead and replace all 6? And what style do I get, I see new and old style, OEM, aftermarket etc. Gimme some guidance please.

Also need a piping boot kit with clamps. Mine are very dry and cracking. Best source for a kit for this is where?

Thanks in advance for any help!

 

Dos your injector connectors have a small metal retaining clip if soo then you will need to get the OLD style plugs because the newer style will only fit new style injectors for later Z32 models.
You can buy the connectors and replace them. But I would highly recommend a whole new harness. I had the same problem connectors here and there causing misfires. Replaced all the injectors and coil pack and it ran fine for a few months and it came back and misfire again. I just had the whole EFI harness replace and now the car runs like a champ no more misfire or hesitation and idle smoother then a new car.
