Hi all,

I was trying to check my TPS this past weekend as I'm having horribly erratic acceleration and power and certain RPM's/gears (auto tranny).

Following Roger's instructions (awesome write-up's btw), I noticed there is supposed to be a dashpot assembly. Upon easy inspection, my engine lacks this assembly completely. There is just a gaping hole there.

My question is this:

If this is supposed to prevent backfiring, and my truck has never backfired, what is the real purpose of this?

Will I notice an improvement anywhere in engine performance if I buy the parts and add this back in?

If anyone has the part numbers or two sense about this issue, please let me know.

Regards,

Justin
