I think I posted this in the wrong location the first time.
I just got a little red VX. 320k miles. The 2nd owner said it was getting 45mpg. He lied- I'm only getting 38!
Tune up: I've changed the plugs (NGK,) wires, cap, rotor, manual tranny fluid (honda grade stuff), air and fuel filter. Seafoam in the intake manifold. Filled the tires with air to 32psi (they were at 12-15psi) Car went from 36mpg HWY to 38MPG-!!??
Cleaned the IACV and TB: http://www.honda-tech.com/showthread.php?t=1575913
Now I'm having idle problems.
-On start up it goes to 1500 rpms then after 2-5 minutes it goes to 1000rpms.
-Once warm 650.
Brakes:
If I'm at a dead stop with the brakes depressed hard and I release the pedal my rpms go up. I've done a break test and everything seems fine.
Compression test:
Cylinder 1- 189
Cylinder 2- 190
Cylinder 3- 191
Cylinder 4- 193
-That's good right?
I haven't checked the timing yet:
I want to get this done, and get the valves adjusted.
Transmission:
-2500ish rpms @ 73-75 MPH 5th gear
-2000ish rpms @ 60-62 MPH 5th gear.
QUESTIONS:
How do I know when the engine goes into lean burn mode and what does it feel like?
Lean Burn?:
-When I'm driving at about 65 miles per hour it feels like I'm getting a sudden boost of power, but it doesn't really go anywhere. Smooths out a little, but it's almost like a loss of power. I know that's contradictory sounding.
I might be imagining things but, on my drive home I disconnected the O2 sensor. (hoping that the rpms wouldn't go to 1500 when I started it, but they still did) However on the drive home it seemed to have lower slightly lower RPMs in high gear and I didn't get that strange surge thing that I mentioned just above. (lean burn mode?)
Check engine did come on, and shifter light went away.
Thanks for reading this and I appreciate your feed back!
By the way, 320k miles and it still has the original clutch I paid $1150 for it. Has a little rust. Did I get hosed on the price? It's all original a far as I can tell.
