Ok i was in a front end collision back in april and i just got my car back last tuesday. I get in today and drive to work and about half way here it starts getting really loud and i notice a huge loss in power and a really loud exhaust like im runnin open headers, it really sounds like a damn lawnmower, its a d16y8. Now what all could be wrong with it? If i didnt provide enough information let me know and I will try to fill in the blanks as best i can.

 

because its a Honda, ull get used to those noises

 

ha, i really need to figure this out before i take it back and start complaining

 

one more thing, my check engine light is flashing. I had this happen one time before and i took off the distributor cap and cleaned the contacts and it ran great untill today. So could that be the problem, or maybe a messed up contact somewhere else? Im just wondering if im on the right track

 

I'm guessing the header is cracked somewhere...

Did you pull the check engine light code to see whats wrong?

 

I did notice a small pinhole in the header when i hosed it to check for that, it was bubbling at this one spot. I can stick a sewing need all the way into the header. My question would be is that enough to cause the hesitation and the flashing CEL? IF so can i just get a guy to weld that tiny little hole closed.

 

Yes x 3

Yes that is enough to cause your car to sound like a "lawnmower". The reason its running like dog *** is most likely because your engine is running in safe mode due to your CEL.

 

ok im gonna go check the codes here in a second then on my lunch im gonna take it up to mercedes which is were the body work was done, do you think i could talk them into putting a weld on that tiny little hole and will that work?

 

that should take care of it, but make sur eyou examine the enter exhaust...

 

Ok i just checked the codes, there were 3

63 - Oxygen Sensor, Heated - Sensor 2 (Secondary) high voltage, low voltage, or slow response

65 - Oxygen Sensor Heater (Secondary) malfunctioning or defective oxygen sensor heater

67 - Catalyst system Efficiency Below Threshold malfunctioning or defective catalyst system

 

Those are all more than likely from the leak. Caddamn obd2 cars

 

Mercedes said i could come up there and use the welder on my lunch break, so im gonna go drill it and plug weld it i guess, or maybe just an exterior weld.

Thanks for all the help guys, and for the quick response, not a good monday for me so far haha.

 

OK well i took it up there and they didnt have anything to weld cast iron so they drilled it and tapped it then put in a screw, did i just get screwed over? No pun intended

 

Whatever can stop the leak...

 

Did the CEL's go away? If they successfully stopped the leak for long term than I dont think you got screwed over. Especially if it's just the stop mani.
