Running Poorly
I have a 91' Infiniti Q45. Lately my car has been running poorly. Here are the symptoms:
1) Rough idle 2) Black Smoke coming from the exhaust 3) I noticed a hard to describe odor coming from underneath the car, smells like exhaust (catalytic converter?) 4) Poor fuel mileage 5) Lacks power. I ran diagnostics using the onboard computer and it flashed a 34 code which the book says points to the "Detonation Circuit". Based on what the technical manual says, there are a few most likely culprits: A) Fuel injectors B) Spark Plugs C) Fuel Pump D) EGR Valve Does anyone have any ideas? |
