Hesitation and Stalling on 89 200TQA

[C1J1Miller at aol.com]

Perhaps you have heavy deposits on the intake valves... initially, the fuel is soaked up by the deposits, leaving the mixture lean; once it's run a bit, the deposits are saturated, and it runs ok...
I think you can have the valves walnut shell blasted in place, or try one of those heavy duty cleaners...

Before you do this, make sure you go through the troubleshooting procedures on Scott Mockry's page:
