The oxygen sensor telling the ECU to run your engine rich.
Actually, this is false. The secondary O2 sensor does not affect ECU fueling at all. Only the primary O2 does. The secondary is only there to detect catalyst efficiency for OBD2 compliance.

Fuel Injector it was!!! Today I changed them and... viola! Car runs like a champ again. Actually since getting the swap it has never run so hard. I thought I was experiencing the raw h22 power but I was wrong. I thought the same actually; that the engine was toast but thank God it was only the fuel injector. I think you should give this a try if you haven't done so already. One last thing though. My check engine light along with my SRS still goes on.

So you're saying that the fact that he has P0420, along with a random misfire code for every cylinder, has nothing to do with one another? Even if that's true, it's worth spending the $4 to get rid of the code for the cat. It would be a start. Then he'd only have 4 CELs.
You do the non-fouler mod yet? Honda won't do it for you. It's something your gonna have to do yourself. Or take it to a non-dealership mechanic and they may do it.

haven't gotten a chance to do anything yet... weather has been harsh last few weeks to do any work on it... hoping to go in sometime this week or next though
yo, the po420 is related to your misfire, but getting your valves adjusted is a very crucial thing to do. if you have aftermarket cams in the the chances of the valves being adjust properly is slim. the dealership won't do it cuz they don't want the hassle of dealing with aftermarket parts. aftermarket of not it is the same as adjusting stock cams. the reason being is the valves are adjust with the valves close. just ask one of the guys at the shop if they can do it as a side job. make sure the engine is ice cold when adjusting valves. should take about 30 minutes to do once engine is cold. yea sounds like your misfire is at an idle. another problem with putting in aftermarket cams is if they don't do it properly the car will be out of time and you really don't notice it running, cuz they will adjust the distrubutor in advance to make up for it. easy check just look at your distrubutor to see if it is turn all the way right or all the way left. honda dealerships usually get tech support from the engineers in torrence, cali. only if a car is still stock, if not they are on their own. do the $4 dollar thing. then check what i've told you. trust me i know what i'm talking about. i've been a honda tech for 8 yrs. i've seen most of the problems. really sounds like a valve problems. there is also one other thing that will cause these codes but it is expensive to fix it. try this first and back to me. pm me.

Our cars aren't adjusted that way. The timing is only adjustable by getting adjustable cam gears or having the ECU tuned. Moving the distributor on a H22 Prelude won't do anything. The timing will always just go right back to what the ECU tells it to be.

When was the last time you took your car in for an OIL CHANGE? My Check Engine Light came on because when I purchased the car I assumed that the people selling me the car kept all the fluids up. I drove like that for a month before finding out that my oil was extremely low.
Go get an oil change and your problem light will go away. You can thank me later.
if the timing belt was installed improperly, by even i couple of teeth the car will start and run. it will have an obvious miss. ppl will try to advance the timing by moving the distrubutor to compensate for the missfire. this will only cover it up from the outside, sounds good, drives ok. the ecu can tell cuz it picks up knock. thats why the distrubutor is slotted for advance or retard. if you don't believe try it and put a timing light on the car and watch the numbers go up or down. cam gears were meant for bigger cams so you can advance the timing more than what moving the didtrubutor will do. please do your research before you make a comment.

I've done plenty of oil change.... if only it was this simple

I've done my research, dude. I have never timed my prelude, but I've done my B16 Civic when I still had it. I know that you can move the dizzy on those to adjust timing, but I've read in a few places that the timing isn't adjustable via the dizzy on H22's. Let me see if I can find examples. I normally don't say things that I don't know to be fact because somebody like you will come along and try to start an internet beef. So let me find examples so we can clear this up. I may be wrong...
I know that, and the engine in question is an OBD2, so it applies. I'm usually not one for arguing on the internet, but that dude (Nhantech) came in here all cocky like "I've been a Honda technician for 8 years...this is how to time an engine...blah blah blah." The only Preludes you can time like that are OBD1's. This is the 5th gen section, not the 4th gens. And obviously the OP doesn't have an OBD1 conversion or JDM swap because Honda dealerships woudn't touch his car with a 10 foot pole if he did, and he's been getting all this work done at the dealership. Nhantech just gave me attitude like he was some Honda King and he doesn't even know how to work on his own car. And then calls me out like I'm the moron.
Hopefully the OP hasn't been taking his Lude to the dealership that Nhantech works at. LOL

hey ppl like you are always making something out of nothing. this thread isnt about you or me. i'm just trying to help the poor guy out based on what i've seen and have worked on. so my bad if your ego is stepped on. as i recall you were the first one to call me out.

When was the last time you did an oil change on your car? Do you check it or does someone else check it? Do you have any oil leaks that you are aware of?
