My fuel economy on my '99 has progressively gotten worse over the last two years, and I've seen a change (for the worse) in the last three weeks. Next weekend, I'm changing the air filter along with Seafoaming the upper end of the engine - would it be helpful to run some through the gas tank/fuel system as well? I'll also be changing the fuel filter, plugs, and wires come February.
My questions are simply, what could be killing my fuel economy, and what else can I do to improve it?
Also, my engine stumbles a bit between 1100 and 1400 RPM, could this play into the problem with the fuel?
One more -will a coldair induction kit improve or worsen fuel economy?
Thanks in advance...
