If I was going to do the tank, I'd pay someone to do it. Not that I can't, it just seems like it would be a royal pain in the *** with little things not going right.

I'll get a filter tomorrow.

Stay away from me until at least 2 days after you change that filter. There isn't any way to come out smelling like a rose

Dropping the tank is a 50-50 proposition on your year.....because of the age. It'll either be a cake-walk, or be a Pita.

I was going to change my fuel filter today, but I think I'll just wait and have my mechanic do it for me when I take the car in Monday.

UPDATE your fuel pressure regulator. There is a TSB out for our engines, accross the board reguardless of 1992 1995. Series 1 regulators need to be updated to a series 2 n/a regulator. It ups the fuel pressure from about 45-49 psi to 52-60 psi. Do that and feel the difference.

Are you serious? I used to have an AFPR for a series II, then figured it woudn't work, so I never put it in. Are you saying I should have kept it?

absolutely, the regulators are the same except for the psi flow rate. I am a mechanic for a living and have seen this few and far between on our engines.. I too had the same problem and when I came across the TSB at work I was like D'oh! But what a difference in smoother idling, and slightly more power, it just helps out the other mods dude. Try it and see, its only like 30 40 bucks if I remember correctly but I have a short term memory problem for some reason... ; )

Just a question, but would this also apply to my 1990 SSE?? I have noticed that is sometimes has a rough idle. It comes and goes though. I know I shoulde be posting in the 87-91 section but I figured since this thread was already started.

It is only rough at idle, once you get going it seems fine. I can probably get the pressure checked later this week. Is the pressure supposed to be the same on the 90 as on the 92-95??
