1986 2.3 turbo cougar xr-7. car runs like a top. the only thing, car stalls on interstate toll plazas/e-z- pass.downshifting right-only after fast,long driving-runs great on city drive.
your best bet is to pull codes,
see my diy link below.............post results.
use a 2.00 12v buzzer in place of the test light or meter illustrated so you hear the beeps.
all you really need is a paper clip.
thanks again-pull codes-now i got brand new tps .
