PO2098 check engine light code
Recently my check engine light came on for PO507 Idle control system rpm high. I replaced the Idle air control but problem
still comes back. I have a PO2098 Post Catalyst system fuel bank 2 fuel trim lean. What do I need to replace to fix these codes? Any advice would be greatly appreciated. thanks in advance Troy |
Is it a 4.7, the 3.7 might be similar.
On the P0507, are you actually idling fast? On the back of the intake manifold there is an elbow - check it for leaks/cracks. Any vacuum leak will make you idle high. That might also be related to the P2068 - don't see that much. It can be caused by an 02 sensor problem, bad PCM, an exhaust leak, or a problem with the fuel injection system. |
plenum leak
I think it might be a intake leak. I already replaced exhaust gaskets. When i spray carb cleaner around sides of intake engine stumbles.
I bought victor reinz gaskets for intake and throttlebody I also got new fuel injector filters. When i take off plenum do i have to remove alternator. I know fuel rai has to come off. |

It does appear you have an intake leak.
You shouldn't have to remove the alternator but it give you a bit more access. You will have to remove the harness though. |
