I no longer have the car, but when I did mine was a 5 speed. I did nothing special to mine to get the 40mpg out of it other than keeping the rpm under 3000 rpm between shifts and keeping the car under 70mph on the hwy. If yours is only getting 28mpg I am guessing that it's an automatic. I had an automatic before the 5 speed and I was averaging 35 to 37 mpg out of it. I think it may be the way you drive it. Not trying to tell you how to drive, but as I was growing up my dad always preached that jackrabbit starts and high rpm's between shifts lowers the gas mileage. I hope that the oil you put in the car is only part synthetic. If the engine is not new, you could knock the main bearings out of the engine using totally synthetic oil. I would dump the oil and change back to regular motor oil. I have for years and will continue to use 10w40 valvoline in everything I own. I had a 67 AMC Rambler when I was a teen and I drove it very hard as most teens do. I was using 30hd Pennzoil. I could not keep oil in that engine to save my life. The car only had 65,000 miles on it. I was talking to a mechanic about it at the shop I was working in and he said the next time I changed the oil to switch off and put Valvoline in. I did and the car stopped using any oil. I was sold on Valvoline products and will never use anything else. Sears Spectrum motor oil is made by Valvoline, if you want to save a buck or two on your oil changes. I hope this little bit of info helps.

I had same trouble and a new window motor did not help! You can split the control box open and inside is a small circut board that has a couple of relays on it. If you study the solder joints under a magnefing glass you might find a joint that looks a little discolored (not shine but kinda flat color). Use a soldering iron to heat pin to that joint and apply some new solder. I pulled new motor out and installed old one back in and walaaa no more troubles

Thanks for the comeback wanger1, Yes this is an automatic with only about 55k on it. I try not to drive it very hard but don't like getting run over in the city. it sounds like the 2.0L is not known for being fast however I think I still have a smaller vacume leak somewhere in those miles of lines. My 89 owner manual says 10-30w straight or syntectic oil. I am using a product Royal purple and I can tell a big difference in the engine coasting or decellerating. Was told by the Napa (now car quest) engine gruru thats its tops in its line. As you tell from my email name I am still into old american iron. Have been driving a 1963 Impala since 1980 that now runs like a raped ape but the gas prices were killing me. Sorry to here you gave up your Honda cuz from what I've been hearing they are a great car for what they were designed for. Like you my friend I run the valvoline racing 10-40w in the chevy but it seems the newer motors are designed with the syntectic oil in mind. You seem pretty smart on these rice burners where I am just trying to figure out sideways 4 clys. open to any and all good advice from those who have already been down this road. Thanks and stay in touch!

I believe that refers to the ...MAIN/Fuel relay....it's actually 2 relays in one module. When you turn the key "on" the Main relay applies 12 volts to the computer ....then the computer applies the voltage to energize the FL (fuell pump) relay.

my 86 accord started idling rough,running out of gas on a hill,have to pump pedal to keep it going.also if you hold it to the floor on highway goes to 4-5 grand & starts cutting out like a rev limiter. i seen on here it could be coil not sending enough juice to the fuel pump.any other ideas? also does anyone know what the vacuum diaphram on drivers side of carb. controls? thanks

we are having about the same problem with 88 honda accord, runs very rough, cant set idle carberator or timing to make it run smooth with out shutting off at stop signs. Have to put in nuetral to keep it from dying. If everything is set to run half way smooth the next time it is started or the next day it will be right back to not running good at all.

First two things to do for both these cars is to check for vacuum leaks everywhere, and to do a simple tune up.
japanese carburetors are very difficult to rebuild and you don't want to go in there unless you really have to.

Immortal O2 sensors?
by circuitsmith

Hi everyone,
I own an '88 LXI hatchback with 217K miles. Needless to say its had many parts replaced over the last 20 years, but it has the original O2 sensors. I'm always reading how O2 sensors should be periodically changed, especially from places that sell them! So, I get no check engine light, I get good gas mileage, as high as 37MPG, and the car runs great and passes emissions. I'm guessing those little buggers would be a PITA to come out after all this time.
My question is are their others who have never changed their O2 sensors? Should I relax about not fixing what's not broken?

Unless you've noticed a conspicuous drop in fuel mileage, no, I wouldn't touch 'em.

i have a 89 accord. carb. ive been having the same problem with the idle for almost 2 years now. its a 5 speed so im able to drive as you said. abit differently. i was wondering if anyone has come up with any solutions for this problem. i have a mechanic that i trust and we are trying to research and tackle this problem. we are thinking its somewhere in the carb. maybe a air intake valve somewhere in there? Id love any kind of feed back. im ready to fix this problem for good.
