Hi guys!! I am new to the forum (and honestly new to any forum for that matter), so I wanted to introduce myself. I'm Trixie, and I recently got a 2000 Honda Prelude! For the most part, my Prelude is in good shape, but there are a few rust spots, which have been sanded out but still need to fix them and repaint. The interior of the car is in very nice condition. I do have a problem with rain/water accumulating in the spare tire well of the trunk, but I think I just need to check the sunroof drain. I absolutely LOVE driving my Prelude!!!! My Prelude was running great... started up immediately, ran smooth...
Until the Check Engine light came on. Now I have this incessant issue with the Check Engine light coming back on after every shop visit, sputtering on initial start up, and running rough when idling at a stop light. I've taken my baby in multiple times to two different auto shops, and they both did the same thing: Replaced the distributor cap and wiring harness, removed and de-carboned the throttle body, and replaced all 4 spark plugs with new ones - three times! The shops reset the computer, the Check Engine light goes out, I take my baby home, but after driving a few miles, the Check Engine Light comes back on. When I take my Prelude back to the shop, the mechanics tell me that the plugs keep getting fouled up... they either check the plugs and clean them or replace them- which is how I've ended up with new plugs three times. I've also noticed that my fuel economy has gotten much worse and smoke coming from the tailpipe. The mechanics tell me my baby is "burning oil because it's an older engine" - which only tells me they have no clue and don't know much about older imports.
I am hoping that someone, somewhere, can provide some insight on what's going on... I love my baby and just want him back to normal :-(
Since I'm a lady, my Prelude is a gentleman ;-) smile
Also, if anyone has any tips on an auto shop in the DC/MD/VA area that specializes in older Hondas, that would be great! Any and all advice is welcome. Thank you!!!

The water in your spare wheel well may be from deteriorated tail light gaskets.
Get the CEL read, it’s free at some parts stores, but my guess is that your EGR and EGR ports are carbon clogged and need cleaning.

Anything from the trunk area seals might of deteriorated over the years. Unfortunate part is the only real way to check is pop off a few of the trunk clips and remove the spare tire cover and hop in with a flash light and close the trunk. Have a friend soak down the entire trunk area with a graden hose and try to find the leak. Remember too though there's some vents on the side that someone may have popped out for whatever reason too, so check those as well. Especially if the surface soaking shows no leaks.

You can do the ghetto check engine light code pull. Which is shorting the service connector with a paperclip, pronged wire crimp or piece of wire. Here's a writeup on how to do it.


Once you can relay what code your ECU is throwing a diagnosis can be worked on from there. I'd assume any Honda/Acura specialist in the area should know this stuff, but definitely quit paying for wiring harnesses, and cleaning your throttle body. Could be that your MAP sensor is going out or you might need to check if you were part of the ignition coil recall (doubtful since yours is a 2000 model year). But pull the codes and work from there.

And welcome!

I second this as well. Get the codes read, get a cheap OBDII scanner on Amazon and read your own codes and that will at least give a general idea of what those codes are. I had a few codes on my car and it was acting weird at idle, it turned out to be two faulty fuel injectors, the codes were cylinder 3 and cylinder 4 misfire and random misfire. I spend money on the distributor cap rotor, spark plug, ignition control module, ignition coil and still had the problem until I swapped the fuel injectors 1 and 2 to 3 and 4 and then the codes jumped to cylinder 1 and 2 with the cylinder misfire that's when I knew it was the fuel injectors. Even though the resistance for all 4 seemed fine the problem was clogged fuel injectors.

Hope this helps or share your codes and see if this is something someone found a solution for.
