SRT Intake Problem (GS430)
Hey guys, I finally got a chance to hook up the SRT intake thanks to passnu2 and 2000Lex. We put all the wires together and installed everything as it's suppose to be.
Now the problem is that the car won't start by itself, I have to give it a bit of gas while cranking it to start-up. Once started, the CEL and VSC lights go off. And the car will not rev pas 3k rpm if it's parked or moving, it hits 3k and cuts right off and bounces.
We got a code for the MAF sensor using a scanner, but the problem is that the car remains on even if we unplug the MAF sensor (does not die), weird!?
I need some insight on what the problem maybe, we are at a total lost...

I like that thread you sent me, try to reverse that wire and see what it does. It the in/out and it may be backwards. Its the MAF that is throwing this off.
Is there anyway to tell if the MAF went bad or is having any issues? Its original with the car but its clean and looks to be in good condition but I know they can be a PITA.
To add to this the car runs great up till it hits 3k rpm (like its hitting the rev limiter). It does also take a little step to the gas pedal for it to fire up. I scanned for codes and its not running lean so that would show the ECU is doing what it should giving the extra fuel for the intake. Habeeb I think you should try to swap the wires you PM me about and reply back to me.

^ I can't seem to find which in/out wire you are talking about, I double checked the connections from the SRT ECU to the car's ECU and every wire seems to be in the right place.

^ I thought so myself but since that one post you sent me said that was a common issue my thinking may have been backwards
Basically all you need to do is switch the wires that are on the wire that is cut so they are opposite what they are now. If that doesnt work put them back as I had them and stop over. That is the MAF wire and that is the issue so this could be a 5 min fix and you are good. Just try it
it wont hurt anything. All the work is done now its PNP from here!!!

ok, we had 2 wires witched around which was causing the non-start issue. We re-wired them the correct way and now the car starts without having to rev up the engine while cranking.
The MAF and CEL problem remains, the car is still in safe mode and will not go past 3k rpm...
Any idea's guys??

yea I am pretty sure the MAF is installed correctly. Unless the 2gen is different I had tried the pipe (alone) on the my 3gen and had it back wards and my car would not start. I had to flip the short pipe to correct the MAF going the correct direction. I would assume this car to be the same. If not then its worth trying. The ECU must be working because the car is getting the extra fuel and not tripping bank 1 or bank 2 from running lean. I keep getting code P0100 (MAF).
His car starts but the odd thing is the car still hits 3k RPM and its like it hits the rev limiter. Car drives smooth up till it hits 3k...nothing makes sense to me. Possible the MAF sensor went bad? Is there any way to check that alone??
