Hi all,

I have a 1992 accord ex with manual transmission and 120k miles. Today driving home, while I was on the 4th gear going about 40mph, I realized when I step on the gas, that the rpm and speedometer wasn't going up and seems like the engine wasn't moving the car at all. Then coming to the stoplight, I kinda floor it and 1st and 2nd gear had no problems. Then at 3rd gear at probably around 40mph again the rpm stopped going higher and stepping on gas kinda like bogging the engine and it was slowing a bit. Nonetheless I was able to drive it home. Does anyone know what can be causing this problem?

Thanks...

 

When was the last time you had a tune up, or just replaced your spark plugs and wires? Sounds like it's not performing up to par because of the possible lack of maintenance.

 

could be your egr ports or your egr valve plugged up with gunk? your engine throwing a check engine light?

 

Last tune up might be so long that I don't remembered. Spark plugs changed 1.5 years ago. Maybe wires were changed too. Not sure what egr valves are. When I checked the car again last night it was low on oil. Filled it up and drove for 20 mins and the problem didn't happen again. Check engine light not on. I was thinking maybe it's fuel injector clogging up because I never had it cleaned. Just punched in a fuel iinjector cleaner from time to time. It was also freezing cold lately, so not sure maybe if there was water or frozen gas in the tank which maybe could of cause the problem. Anyway, I'll drive again tommorrow to see how it is. Haven't really been doing proper mainetenance on the car because I am picking up a new car in two days, therefore I probably won't be driving the accord much.

 

check this out. im planning on doing this also on my 4th gen, is your acceleration kinda stuttery?

Air/fuel mixture. It could be timing, plugs, wires. But most likely its just a severly dirty air filter. When you floor it the engine dumps fuel faster than the extra air is getting to the engine. This causes the initial bog. Then the engine has to burn the extra fuel before the bog goes away.

 

Shouldn't be air filter. I have those washable cone filters. I mean it's dirty but definitely not severly dirty to a point it's affecting the engine.

 

Acceleration is fine. Just not sure what happened that night. Drove it a couple times afterward and it doesn't happen again. Hopefully it doesn't come back...hehe =)

 

Oh well, problem was back briefly tonight. It was doing it on 2nd gear today. Rpm wasn't moving at all when I stepped on gas. It's like as if nothing is feeding through the fuel injector. Then keep stepping on gas and then rpm went up again and the car felt like it kinda pick up traction all of a sudden but it skid a little because it picked up speed while the rpm wasn't really moving.

Anyway, picking up a new car tommorrow. So the accord will probably sit a while before I get the chance to bring it to shop. At this point in time the car is so old, I wonder if it's worth investing anymore maintenance money on it.
