What spark plugs should i use with the few mods i have? Autolites or TR55s?
Prefer one i can buy at advanced or oreileys. Also do they have decent plug wires at those places?

Problem is...
My car has been getting less and less peppy when i push the gas down. Like it falls on its face and almost feels/sounds like its sputtering out. I figure its the sparkplugs. This happens anytime i push the accellerator down at any time. ???

Thanks!!

autolite 605'*. the cheap ones at walmart. 6 for 6 bucks

autolites are a good choice to go with

Autolites!

You might also want to check out how clean/dirty your MAF is. I had the same issue (among other driveability concerns) with my Bravada and it was entirely caused by a dirty MAF (mass air flow) sensor. On the bravada, it is an open element MAF, but in the Bonneville, you can't really easily get to the elements to clean them. The easiest thing to do is get some Throttlebody/Carb cleaner (O2 & CAT safe) and spray the living crap out of them until they look nice and clean. If you think that you can get a q-tip up around the elements, then that would clean off any stubborn debris, but be very careful. Those elements are very fragiile and easy to break. And the MAF is $$$!

Good Luck!

With the mods you have, it wouldn't hurt to run Autolite 104s (2 heat ranges colder). I'm running those and haven't had any problems or codes.

How do i get inside to spray the MAF? There is a screen that is on the outside...do i have to take the whole throttle body off?

No, but you must remove the MAF from the TB. You will need a set of safety bits to remove the screws for the MAF though.

What'* a MAF is that like a MILF!!

Um... No nothing like a MILF... MAF==Mass Air Flow so the MAF sensor is the Mass Air Flow sensor, but a quick search would have yeilded the same answer rather than posting a basic question that didn't need asking.

milf'* are more fun!
