was running horrible after a money shift/over rev. sounding like a harley. with a cylinder 2 misfire CEL. replaced the usually things. kept running horrible for months. now CEL went away and car is running great out of nowwhere. can it be my ECU?

 

What's your setup? I also have a '97 SH and had a similar problem with a faulty ignition box from MSD; so in my experience it could be something in your ignition, especially if you're getting a misfire CEL. Not sure why it would go away though; fouled plugs or short somewhere maybe?

 

idk it was weird . ever since the over rev i thought i had a bent or cracked valve cuz it ideled horriible and threw a cylinder 2 misfire. now after replaceing plugs and wires and cap and rotor and no differnce. i would even erase the code and it would come back. and then suddenly 2 months later one night jus dispeared on my way home and its running perfect. very weird, i was getting ready to swap it cuz it was so annoying. and by the way its bone stock.

 

possible the crank sensor or the ignition mod

 

Question.

I have a 1997 prelude, doing heavy reading and Hacking my car bit by bit.

I keep running across the SH designation during my research. What does the SH mean?

I have a Japanese made 97 Honda prelude automatic 2.2 vtec with few race mods.
Does mine qualify?

Thank you , I am new to this

SH stands for Super Handling and these cars are equipped with ATTS. (I won't get into expaining that system. Search it) They only built SH's with manual 5 speeds USDM at least. I'm not sure about JDMs but I doubt yours is equiped. Sorry Dude.
