i have no idea, its been doing this since i took it to the drags , i have not check the compression yet

but the car definetely using more gas than before , is it because i just installed a custom 2.5" system ??? altho i have the exhaust since like 2 months ago

and also it feels lazy when take off

ive changed the spark plugs with Denso Iridium , same heat range as the replacement , according to the Denso catalog anyway ...

ill do the compression check hopefully this weekend, what sort of #'s should be expecting from a 96 JDM R engine ?? its done 130k km

thanks for reading this

 

Bad gas? New fuel filter?

 

u think so opie ??

the car has done 130,000 km ~ 52,000mile

and im sure it still has the stock fuel fiter

 

Couldn't hurt, it's cheap enough.

How long has the problem been going on? Any mis-shifts or similar incidents? Do j00 have oil for the v-tack!?

 

Air Filter, does it need to be cleaned or be replaced?

no i have never mis-shifts , altho ONCE i tried to do flat shifting from 3rd to 4rd @ the drags , it went it smoothly , u think that would cause the problem ??? i still have the rev limiter

the problem is been there since i took it to the drags ....

and air filter, uhmm all i can say its pitch black , LOL still on stock filter

 

Get a new filter, see if that helps at all. The powershifting wouldn't affect the motor I think, just the tranny.

 

replace teh air and fuel filters, change oil, and maybe give it a bottle fo fuel injector cleaner - 50,000 miles is a long tiem to go on filters, no matter what honda says.

 

the air and fuel filters are 'supposed' to be changed every 30k

 

did you also installed 2.5" header? if so, i'm thinking your a/f ratio is off. might wanna double check your a/f ratio. since bigger piping tends to Reads more exhaust flow. Also you might want to consider doing your valve adjustment again. As you stated, you went to drag race.

Flowing more fuel into engine has nothing to do with dirty fuel filter.

He installed exhaust, not a header

Change the air filter and fuel filter, you will be surprised what a difference it can make

 

alright i will change the fuel filter and air filter

and regarding the 2.5" header , my motor is a stock 96 jdm R , comes with the stock 4-2-1 header with 2.5" collector already

thanks for the help guys

He doesn't learn. LOL!

 

I'm thinking it could possibly be the 02 sensor or a clogged cat? Also check timing.

 

might need a valve adjustment..... just an idea. Also might need to adjust the fuel pressure....

Yea, this would cause the car to lean out, using less fuel, not more!

more often than not a dirty fuel filter makes the car run stupid rich. I can't explain it, but it happens. I wouldn't believe it if i hadnt seen it multiple times myself.

I used to have a few articles on the subjet, but the server is gone now.

 

Stock timing is 16 +/- 2
