[tech] need help! Car bucking on the hwy

[longcoeur at yahoo.com (Patrick Bureau)]

Calimus, funny how sometimes the simplest and most obvious a head banging problem can be missed. not that in this case it did, but it helps to ensure I have not missed anything, so every little bit of help does in fact help. cheers
 
the intake filter on the transfer fuel pump was changed at teh same time I changed the pump and hoses. :) it was actually my first though about my problem. thank goodness for 24 hrs autozone's
