I put in a can of BG 44K in my fuel tanks about a month ago,
ever since whenever I accelerate quickly, e.g. merging onto the highway
I get a P1283 code, This has happened 3 times since the 44K was put in.
If I drive like an old man for ~200-250 miles the warning clears.

Also I get 7 MIL codes
Misfire
Fuel
Comp
Catalyst
EVAP
02 SNSR
02 HTR

any ideas???

the P1283 is a lean warning, I figure that it was caused by the 44K. I figured I'd ask for others experience.

 

first clean your Air Flow Meter- could be Faulty Air Flow Meter.

 

How many miles are on your car? I'm wondering if the 44K loosened some gunk up inside the tank and its clogged the fuel filter...I've heard of it happening on higher mileage vehicles.

 

P1283 is related to the driver's side O2 sensor. Sounds like you're getting more than just that code though.

Possible causes are:
- Air fuel ratio (A/F) sensor 1

- Air fuel ratio (A/F) sensor 1 heater

- Fuel pressure

- Fuel injector

- Intake air leaks
