Alright... i have a 1993 honda prelude si w/ 207,000. first gear is fine, but 2, 3, 4, and 5th if the pedal is only a little bit down for normal around town driving the engine putts. it's like someone is cutting fuel and activating it several times in a row. now if i increase throttle on her, it's smooth... what's the prob? thanks!

 

I would start with plugs wires cap and button.

 

is the check engine light on?

 

1. So you think ignition is the source of the problem? That's what I was thinking. I was also thinking of running some injector cleaner through the gas.

2. No the check engine light is not on.

 

it sounds a lot like the o2 sensor is going out.. Mine ran crappy at narrow throttle, and ran fine at wide throttle. A few days later, it did eventually throw a check engine light, and changing the oxygen sensor fixed it.

 

Is there only one o2 senser?

 

on the '93 the single O2 sensor is on the exhaust pipe under the oil filter. You should usually throw a code 43 if that is bad, though.

 

I appreciate it. I'll go ahead and replace it anyway; with 207,000 I'm sure if it hasn't been changed yet it'd be a good idea. Thanks to all... any other feedback or possibilities is VERY welcome. Thanks again.

true

on my car, it started running crappy at partial throttle about 2 weeks before i got code 43 (fuel supply system) about another 2 weeks went by and then i got code 41 (o2)

 

Did you do anything about the fuel supply code?

 

a faulty o2 sensor will fool the ecu into thinking there is a fuel supply problem, thus a new o2 cleared both codes 43 and 41

 

I replaced the ignition wires and the the spark plugs... it's still doing it. Any other suggestions? I'd like to sell my other car, but i can't with this one screwing up.
