Hey guys,

Just finished installing the header.

I right away have problems, the CEL is coming on..
The engine is overheating..I have no idea why.. Radiator fluid is topped up...everything seems to be in working place. Put everything together back the way it was...

The only thing thats not connected is the o2 sensor that is meant to be on stock headers.. is this meant to be connected somewhere?

PLEASE HELP.

Sounds RASPY and VERY embaressing.

 

Did you drain the radiator fluid for some reason? I know you shouldnt have, but you mentioned it was topped off.

You should have that 2nd o2 sensor in, also are you using rrms elima cel, also did you try resetting your ecu, remove the battery wires for 10 minutes, then put it together, let the car idle and relearn its parameters, then turn it off, turn it on and voila.

Also I would get your code read, but its going to say o2 malfunction, but it should not be overheating.

is your fans turning on?

By anychance is the header touching the water pipe/pump?

Thats all ive got.

Your prob have an air pocket in your plumbing somewhere. Start the car after it's cooled for a bit, then while the engine is running take off the radiator cap (carefully) and see if that "burps" it. You might have to squeeze the tubing a bit. I can't imagine it being anything else?

CEL will def come on without eliminator. You can make one with two spark plug anti foulers like I did, or just buy one from RRM.


To reset ECU, just disconnect neg terminal and hold foot on brake for 30sec or so. No need to wait 10min!

BTW, I warned you about the sound... you will def need a second resonator and a high-flow cat to tone her down.

 

Guys, thanks.

I have the RPW headers.

I drained it because I had to remove the radiator, but its now being topped up..

The thing is CEL came on right away.. I don't like the looks of that, most of the guys here have it come on about 400-600kms into the driving.

The raspiness is blo*dy terrible. It is so bad, like it is just unbelievably BAD.

Also, is the o2 sensor in the engine bay meant to be conencted? IF SO, WHERE PLEASE...

 

Headers not touching the water pipes..

Fans turning on..

The only thing not connected is the FIRST o2sensor in the engine bay. The other in the high flow cat is connected..

Yes retro you warned me, I have a HIGH flow cat, no resonator as yet, but man retro, is AWFUL..

 

Huh? There's one pre-cat and post-cat, that's it. The second one (closest to your muffler) is the one that needs the O2 fix. The first one is screwed into your header.

 

The RPW headers don't have a screw in port for the o2 sensor in the engine bay on their headers...

What should I do?

 

well, the reason why you are overheating then is because you have air in your system, just take off your radiator cap and let your car idle, it will all bubble out.

 

What about the o2 sensor in the engine? Where should that go?

 

Doesn't RPW put the O2 sensor in the header as opposed to the downpipe like RRM? I'm not real familiar with their products, but it's gotta go somewhere!

 

I think the CEL is not about the o2 sensor. i put in my header and drove it for about 150mi. before i threw the CEL (due to no cat). i dont think that not connecting it would cause it to throw that much quicker.

 

Both O2 connectors must be connected, ESPECIALLY the first one. That's the one the ECU uses to adjust for fuel and that's why you got the instant CEL.

 

Okay, so made a few mistakes.

The radiator fluid I thought was topped off actually wasn't. So I topped that up and CEL turned off and car was running fine. Then I had to make extensions for the o2 sensor to go under the extractors. Once that was done, engine was quiet and running smoothly. Thanks to all.

Just a heads up. If anyone of those sensors is NOT plugged in, RASPINESS is your best friend. Once all are plugged in, you've been cured. Holes in the exhaust pipes are the cause.

Took her for a light spin, filled her up and took her for a real spin.

Gains really noticable in mid-top end. I noticed when I was driving in second gear, the car was quite responsive, and about 4000rpm this is when the car started to pick up. Engine resposiveness is not as quick as usual around 1000-3000rpmish, but after that - the revs start to pick up quite fast. If your idling in second at about 3000rpm and then floor it, THUMBS UP. To sum it up, its more of a smoother power band. I believe I've lost low end power, not much but noticably enough.

Next comes the catback and exhaust this week or the next. Should be fun.
