Engine loss of power?

1.6 ls non vtec engine honda coupe. Failed on emmisions test. Results low idle; CO 3.30vol% HC0ppm lamba 0.889, high idle CO 3.89vol% hc 232ppm. Took it to a garage and the mechanic said it is putting alot of fuel out the exaust, car is not fitted with a diagionest plug, some werent in that year. The car does not seem to be running that bad but sometimes lacks power, and then surges. Please help with any ideas

I have a 1998 Honda Civic Hatchback DX with 175,000 miles on it and the car works great, but I find that the pick-up lags when the fuel tank is full and picks up when the needle goes down to 80% capacity or less. I believe this is what's explaining the slight differences in my acceleration from one set of days to the next. Is this to be expected? And why?

Start fine and drives but want to get up to about thirty miles per hour it seems like it loses power gets real sluggish.

I have a Honda Civic 1998 with 102,000 miles on it, my check engine light came on and ever since I have problems with accelerating. I will put my foot on the gas and my car will kind of jerk like its trying to get gas but cant, so can anyone give me a idea what this could be thanks. Also had tune up about 5 months ago so I know that shouldnt be the problem.

I have a 1998 Honda Civic HX 1.6L MFI VTEC-E with 150,000 miles on it. I have had no real problems and done all maintenance as I should. One day it wouldn't start and I had to get a jump so I thought it needed a new battery. I replaced it and I'm still having issues. When the car is idleing, it idles a little low. If I turn the air on it drops a lot more and tries to cut off. I took it to my mechanic and he said he thinks it's a sensor but didn't know how to change it. Any ideas what this could be or what I need to do to fix it. I have a friend who works on cars and I'd like to be able to take it to him and tell him what to fix. Thanks in advance for your help!

I have a 1998 civic LX 140K with automatic trans,
Just recently, I noticed the engine light come on then seconds after the speedometer went erratic just jumping all over the place and the motor started to bog down (idling up and down and almost chocking).
I replaced the computer with no change and tried to find loose connectors but dont know where to start.
Please Help
Thanks Vince

Engine Performance problem
1998 Honda Civic 4 cyl Two Wheel Drive Automatic 130.00 miles

My '98 Honda Civic has a very strange problem, mechanics can't figure out.
When it's cold, it usually runs perfectly, but as soon as I start driving for a few minutes, first the rps start jumping up and down out of control, then the car starts losing power when you accelerate, and starts jerking, it never turns off, but it jerks badly, it's not the transmission, because it does the same engine sound when you accelerate with the car parked.
The car sounds fine in idle, when you accelerate is the problem, it has some sort of broken sound coming from below(maybe the catalystic converter?)
Check engine gives codes of 300-304-ign misfire and 1399.
Replaced cables, spark plugs are fine, distributor, timing belt seems fine.
Dont know what to check anymore
I appreciate any help, thanks!

My car does not want to accelerate

My 1997 Honda Civic doesn't accelerate when I push the throttle down normally (it bogs down). If I push it down very slowly it will accelerate fine. Anybody have any ideas?
