2.2 TBI runs rich on starting

Filed under: Uncategorized — admin @ 2:38 pm

I would greatly appreciate any input concerning the following
problem with a 2.2  TBI engine in my ’88 Horizon.
The engine runs too rich diring crank-up, and for some time
after. A couple of times (in 7 months that I own the car) it
even wouldn’t start because of flooding. The overall gas mileage
isn’t bad however: 25-26 mpg (auto transm). The symptom is more
likely to show up wheh the car is started hot, or with a cold
engine, when the ambient temperature is warm. The condition got
better after replacing the oxygen sensor, but hadn’t gone
completely.

Thanks to all,

Alexander

    Tune up the carb by changing the ratio, you should probably turn down the
    fuel instead of turning up the air though.  It will take alot of
    time to get it right, but when you do you will see better overall
    performance.  I had that problem with my 86 Charger with 2.2L.

    After I tuned up the carb, I drove to Ft. Lauderdale, Fla. with the
    air condidtioning most of the way and I pulled off 33mpg!!!!!  I miss
    that car :(

    My sister had the same problem with a 2.2 shadow, we took it to a dealer and he
    just said, "it could be this, or it could be that."  Finally we just unhooked
    the wire to the injector and put a toggle switch in the line.  Every time the
    car wouldn’t start, usually dead of winter in high winds, she would pop the
    hood, flip the switch and the car would clean itself out, then flip the switch
    back on and she was off and running.  We owned the car for 2 years after
    installing the switch and used it semiregularly, 5 or 6 times a winter.  We
    sold the car and told the guy the story and the car still runs perfect.
