poor gas mileage
im only getting about 10 miles to the gallon on my 87 bronco 2 4x4.Just had a major tune up and cat converter done among other things.Im also having to push it hard on the highway before it "catches." what on earth could cause this? could a vacuum leak cause that as well? i can hear a what sounds like air sputtering out when i push it.Other than that the engine purrrrs.

i usually get around 18-23 mpg with my 86 b2..i had a similar problem back in feb of this year,i couldn't keep gas in the tank,come to find out the pressure reg was leaking fuel into the oil, i learned on that one. also i found some leaky fuel injectors,i replaced them all,it runs like a top now

I do not smell gas.All i smell is oil from the leaking valve cover gasket.The truck WAS running rich but after $1300 of work thats been fixed, so no smoke at all.I do know it needs an air idle.How would i check the regulator? Injectors? How much am i looking at to replace these?Im so frustrated, what started as a good deal has already cost me 2k and its still needs work! Please help.

take the line loose at the pressure reg going to the engine,if you see or smell any fuel,then the reg is bad. it is located on the right rear corner beside the plenum if your looking at the engine. this is a common part to fail

Do you have a repair manual yet? If not, it would be a good idea to get one as
they have illustrations of the parts and systems itht you may need to get to.
they also have procedures for the troubleshooting and repairs you may need.
I've found the Haynes manual to be the most complete of the aftermarket books.
Also, did they say what the air idle was, that you needed ?
