Quick question about 6 bolt maintenance

[horizontalkev]

I have a 99 GSX with a 6 bolt swap, I want to change the o2 sensors, plugs (NGK) and wires, and so on. Reason being I have bad gas mileage and running rich, and throwing a code P1105 (fuel pressure solenoid malfunction) and trying to fix it, and possibly my crazy gas consumption. What else can I do? And when shopping for motor goodies what year eclipse do I refer to, early 90's? Thanks

Well first start by fixing your fuel pressure solenoid to get rid of your cel.
That will be a 2g fuel pressure solenoid.

It depends on what parts your looking for to upgrade.
Is it a 6 bolt long block or does it still have the 7 bolt head?
What exact performance parts are you looking to upgrade, then I can tell you what to look at.

Im thinking of bypassing the solenoid will that adversely effect anything negatively? And I don't want to upgrade anything right now just replace whatever is causing my bad mpg, any ideas? Could the P1105 be a factor? And I don't know how to distinguish between the 6 & 7 bolt head how can I tell. I have a T28 running 16PSI, and I run 91 octane, maybe the octane is too low could that make it run richer?

Get rid of the fuel pressure solenoid, that is if you dont mind having the CEL. It will not affect anything, except cold starts A LITTLE, you may not even notice the difference.

The CEL bugs the hell out of me. Shouldn't the light stay off if its electronically connected?
