Please help jb2 problem

Elie335 · 05-06-2010, 09:32 PM

Hey everyone, I recently installed Jb2 pin-out done by myself. The car started and had no problem at all, went for a little cruise to try it out the car didn't had any problem from 0-70mph, after accelerating more then 70mph, i got the engine fault reduced power thing, i pulled over turn it off and on again and it was gone. But the engine faults keeps showing after accelerating more then 70mph... anyone knows what could be the reason?

Is this an actual jb2? If so did you install it with all the wires?

yes its a jb2, I installed the yellow and black ones only as the instructions says.

Check the code with a BT. JB2 requires the vacuum line changes so maybe an issue there?

Vacuum lines will cause 90 percent of the prob - taking them loose can cause cracking if they are old.

Pengwin · 07-13-2010, 11:26 PM

I double checked all my vac lines and they are still good. I removed jb2 from the car and did many wot and no engine check light. Car runs as nothing was wrong.

Suggest you find someone from your regional area that can use the BT scanner to check codes.
