Hey guys the other day I was taking my prelude on a road trip. I was driving for about 100 miles and then all of a sudden my exhaust tone changes and it gets extremely quiet I could tell the vast change in tones because I have a 4 inch apexi n1 exhaust on my lude. Stupid me continues to drive thinking its just my hearing but I continue down the high way for about 10 miles and all of a sudden I completely loose power I try to rev it up to keep it running but bam I lost all power the car shuts off lost power steering and everything it just bogged down and sounded like it sputtered out at this point I was fucked I pull it off to the side of the road thank god I wasn't on the hilly part of the high way. I try to start it back up but damn did it sound rough it took several cranks to start it and you had to constantly rev it to keep it running it would only last for about 10 seconds and it would just give out. So at this point I had to wait 4 hours for a tow truck I get it off the bed when I get home and try to start it out of curiosity and what do you know it starts right up but the tone of the exhaust is still very quiet and it feels like it almost has a loss of power I didn't drive it yet because I still don't want to risk possibly causing anymore damage. It idles normally but it just doesnt sound right there's no knock or major ticking and I am stumped I am no great mechanic but I'm usually able to figure out where the route of my problem could be but with this problem I have no idea I'm tired of looking out my window seeing my lude just ist there any help or ideas would be greatly appreciated.

 

Do you have any diagnostic tools?
Basic tool set?

I mean its hard to help someone that has nothing.

 

I do not have any diagnostic tools but I can get my hands on some. I have tools but I just need some ideas on where to start looking or what it could possibly be the problem.

 

a basic tuneup would be a good start, including a valve lash adjustment and oil change. and when you drain the oil, drain the oilpan first before the filter, and drain it into a clean bin. the oil should be black, but clean. if it comes out looking like metallic car paint, there's an internal issue, possibly fried the rings, or something else. after this inspection, then you can drop the filter and proceed as a normal oil change.

after the oil change and valve lash adjustment, do a compression test. and don't forget to remove the ecu fuse and backup fuse from the underhood fusebox before the compression test, this will disable fuel and spark. if compression numbers are out of spec, then the piston rings are probably cooked.

if everything is good so far, including compression test, proceed with the tuneup installing new cap and rotor, and sparkplugs making sure they are gapped correctly to stock spec and ONLY use NGK plugs, nothing else. and new plug wires too if you think the old ones may have an issue. get NGK wires too if at all possible, they will outlive the car itself.

hopefully you'll find the issue with something above.
this is all assuming you did not get a check engine light, and don't have any trouble codes store.

 

Thank you very much I'll check into all of that tomorrow.
