Ok I have a 01 prelude and my engine light came on for misfiring. I replaced the plugs and wires from advance auto parts. and before i did this i was fiddling around with the old wires and pushed them down harder and the light went away but i bought new plugs and wires anyway. but that didnt resolve the problem. I called honda and they told me i need NGK plugs and that should fix it. well it definately improved the throtle response and no more lag but i kept the wires i got at advance on andi think that they are cheap wires and thats why its still misfiring. but just recently my maintenance required light turned from yellow to red. And i'm worried about this cuz i changed the oil last week and I checked it today and it was only up to the 1st dot. I never went threw this much oil before. Any ideas from anyone I would really appreciate it. Thanks

This is nothing more than a reminder to maintain your car.

 

Yeah, get some NGK wires, they fit perfect.

Check for oil leaks on the engine, and of you have none you are burning it somehow. Maybe VTEC, maybe bad rings, could be different things....

 

Yes I know i Have been maintaining everything i'm suposed to I parked it for the winter and before i drove it changed the oil and made sure nothing was wrong it was running good. and i looked for leaks and there were none under the car or around the engine. i only got on it a couple of times racin a 2000 and an ss cobalt stage 2 so i thought that had something to do with the oil but damn a full line in a week. So red light on maintenance is a problem or no. I mean its not like its knockin or parts sound like they'll break and no smell anywhere.

 

Stage 2 Cobalt = stage 2 oil loss

 

You should go to someone who is ASE Honda certified and let them check your car cuz apparently no one here knows what's happening with your car, some just post stupid coments!!

Yeah, stupid comments just like yours, but you went one step further and added incorrect spelling.

It can be pretty difficult to diagnose car problems over the internet when you cannot see, hear, touch or smell the vehicle in person....he probably should take it to a good mechanic.

Just what I was talking about!!

 

play nice

 

Well that light for your maintainence has nothing to do with any problems you may or may not be having with your car. It comes on a different milages (green to yellow to red) to remind you of maintainence items due at certain milage intervals. To reset it you just get your key and push in the black thing next to the little square that is red on your cluster.

About your misfire, I doubt that having NGK wires vs autozone is going to solve the problem. I personally like NGK wires better however if you have new wires that fit correctly, 99% of the time its not going to be your problem. If you suspect they might be the problem get a multimeter and ohm them out if they are in spec your good to go. Just make sure like I said before, they fit correct meaning that when you push down on them you hear or feel them kind of click into place. Also make sure that your plugs are at the correct gap. Look at your cap and rotor to make sure they are in good shape. A misfire doesnt have to be ignition related though. Check your fuel pressure and make sure your getting the correct AF mixture. You can look at primary o2 sensor voltages to figure out aproximate AF ratios.

Did the code come up as random misfire or did it give you the cylinder number itself ?

And finally your oil problem. First off make sure you dont have any big leaks. The next best thing to do is a compression test (dry followed by wet). This can tell you alot however it may not. If you still havent found your problem then try a leakdown test. However there are still some things that are hard to diagnosis using all these tests. Keep an eye on it and keep track of your oil consumption. H22s are known to burn some oil (more if you drive like a dick). Also what brand and weight oil are you running ?

 

I was receiving misfire code with a CEL and it was my EGR valve. As for the maintenance required light, it is only for oil changes. It changes from green to yellow/amber at 7,000mi (when Honda recommends an oil change) and turns to red at 10,000mi. You stick your ignition key into the slot on the gauge cluster next to the light to reset it like lude98sh said. If you do this every time you change your oil it will always be green (unless you go 7,000mi like Honda recommends for an oil change) in which case it would be yellow/amber when you change the oil. As for plug wires I would use OEM - honda part# 32700-P5M-003 WIRE ASSY., IGNITION (SUMITOMO) $59.99 (5th gen), and I would get the NGK SPARK PLUG (PZFR6F-11) (PLATINUM) (NGK) plugs at Advance Auto PDQ $9.99 each since the dealer wants $14.26 each.
