Porting the Intake Manifold

[NewZJ]

When you get a misfire code, check the fuel injector plug for that cylinder. It might not be pushed on all the way and can come loose after some driving.

I got a ton of codes and missfires and the car was not idleing well. Popping and not revving. I cleared the codes. The car was perfect after that a d has been for 10k miles with these two mods

Your unhooking a ton if sensors when you do the intake mod. That's what most of the codes are from. Clear them you should be fine.

I just performed this mod last night and I must agree with everyone it definitely improves the top end pull. I got it done in just over 2 hours (30mins of it was fighting to get a bolt I dropped right between the starter and block) but other that that really straight forward mod just like everyone said take your time and clean out the mani really well before reinstalling. Well worth it!

On my way to work today, I got a p0266 code, I cleared it and it still was limp and only getting 5 pounds of boost and over heating, I turned it off and let it sit for a while and then the car was fine, didn't come back on during the drive home and the car drove fine.

Throttle position sensor. Could be a fluke could be going bad.

Po226 looked at code wrong.


P0266 Cylinder 2 Contribution/Balance Fault

Misfire cylinder 2? Check spark plugs.

Yep it needed new spark plugs, there was very little gap, car accelerates much better now.

If you have anymore problems have someone check the gap tool cause some cheap ones will not be correct seen that on trifecta fb page.

Ok now im having another problem, the car starts to spudder at 4k.. It starts to spudder and jerk a little when i go 4k and up.

What kind of mileage do you have on your spark plugs. Sounds like misfire. Trifecta tune/ high boost will slowly degrade your plug gap. Start by checking your plugs and making sure they are at .028"

I just changed them today, I think I have a leaking valve cover gasket because oil was down in the spark plug well.

 

[Kuntryboy865]

I ordered a valve cover gasket because my old spark plugs were covered in oil and there was oil in the spark plug well, so whenever that comes in i'll install that. i'll also hit up advanced autoparts and pick me up a spark plug gap tool and check.


Edit.

Well the spark plugs are gapped properly. If I give it half throttle it pops and stutters and it seems to do it more in 3rd in manual mode. Maybe running lean?

 

[krakenredbeard]

You need to make sure the gap tool is accurate. A lot of those cheap disc tools are inaccurate. This may be why your still having the issue the guy on the trifecta tune fb page said his problem was cured and it was doing very similar to yours. But his gap tool was wrong.

If your crankcase isn't sealed well i.e. dipstick isn't sealing, oil cap has a bad rubber ring or..... valve cover gasket isn't sealing, you may be pulling in unmetered air.

How's the idle?

I fixed the orginal problem now im getting a P0299 cel. Underboost.

I used to (about a year ago) occasionally get that code. It seemed to only happen on hot days with the A/C on when I was getting on the freeway full steam after work.

I cleared it each time. Changed nothing else, found no problems and it hasn't been back since.

Obviously, inspect for boost leaks. But if you clear it and it doesn't come back often, I wouldn't worry too much.

I hope it doesnt come back

If it continues to return then return to stock and when the code comes back take it to the dealer. It and the underboost code are often associated with a sticking wastegate which requires a turbo replacement.

In the meantime just clear it, flukes are quite common in the car world, so don't worry yet.

 

[Sneakerfix]

Have you checked the coil pack springs? Also was their oil down the walls of the spark plug holes? Or only on the plug threads? Even if the p0299 is a fluke I would just let them replace it.

Just joined the club of those that have ported, WOW.
