RE: Lousy fuel economy on '91 200TQW; advice, please.
Thanks for the input so far (however limited). I suppose I should do a
backpressure test on the exhaust, though I doubt this is it. The exhaust
seems okay, and there are two cats on this car in parallel. Perhaps
another option is to throw another O2 sensor on it that hopefully leans out
the mixture a bit. The mystery to me that the exhaust is very very clean,
so is emissions, yet I'm barely getting 13mpg around town.
Is there an easy way to tell if an injector is leaking? (the injector
solenoids are working fine)
