Earlier today the car started throwing a fit when I left the neighborhood. I was sitting at a stop sign ready to pull off when “reduced power” message came on along with the CEL and once I started to take off from a stop it seems to have started misfiring. Looking behind me I noticed a little bit of white smoke from the exhaust. Very strong smell of exhaust inside the vehicle. Immediately turned around came back home. Let the car sit for a while turned it back on and it was running fine, although the CEL was still on.
Here’s the codes I found P0089 P0087 and P00420, the 420 has been on there forever but the 87 and 89 are new. On my way to autozone to get the codes pulled I gave it the beans even uphill to see if I could get the issue to come back, ran absolutely fine.
I know the 87 means low pressure at the rail but is it perhaps possible that a stuck open injector could cause the low rail pressure and white smoke? Fuel filter? Pump?
