check coil packs and injectors

check to see if the plugs are gapped correctly. If its been a while since they have been replaced i would recommend changing them. Its cheap and easy. Most of the problems i get from people that bring their RB to me is improperly gapped plugs. also check to see if you have any leaks in the vacuum system.

The problem is that it's an RB20.

i had same problem, mine got worse. it ended up being the coilpack harness. got one from wiring specialties for like$60

Yea is was the coil pack, it overheated, i guess that is a comon problem and im scared to buy another one for 80$ and it burn up again. What is the cause of that? so i can avoid that happening again.

goldendrift · 11-24-2012, 03:32 PM

This is it. and if anyone has one i will buy.

stamps31757 · 11-24-2012, 03:56 PM

thats a coil pack. I would check with rawbrokerage to see if they have one. They are more than likely going to have it. They deal with RBs

trickey1991 · 11-24-2012, 04:57 PM

you might also want to check the ignitor. the stock ones on rb20's are just. you could replace it with one from a turbo 300zx.
