'92 Honda Civic VX h/b [/align]
[hr]
I've done a 'search' on here, and couldn't find a similar model, and didn't know if that would make a diff. in the possible solution.

I have '92 Civic VX h/b 1.5 manual (engine D15Z1) 174K miles
My problem is: Will run fine, then idle REAL low, almost
stalling. The Check Engine lite comes on...i've coded it, i'm getting 9
& 48. called dealer code 9 isn't a free standing sensor, its a
component IN the distributor. I don't think its that, as the previous (and first owner) just replaced that about 1.5yrs ago.

I'm thinking it may be my 02 sensor,(code 48?) and thru searching here, have found some sources for acceptable (by no means good) prices on the 5 pin part L1H1.
[/align]I've come to find out that dist. on this model and like models around this year tend to fail. re: code 9

I'm also getting really HORRIBLE mpgs....like 30mpg avg on tank, and I
do 75% hwy driving. My '94 DX h/b 1.5 manual w/ 212K miles gets about
36-41 mpg on avg per tank...and is what i'm using as 'comparison' for
mpgs vs. the '92.

The previous owner has kept meticulous service records, done ALL scheduled maintenance as outlined. I haven't checked the sooty-ness of the plugs, and hopefully they're the right ones for the VX (i'll check to see)

I've also noticed it EXTREMELY powers down going up hill in comparison to my '94 DX.

The prev. owner still has the window sticker in all his paperwork and it states it's a vtec-e engine, but the engine itself does not have the words vtec on it.

Thanks for all or any answers[/align]
