when i down shift to first and hit vtec my engine shuts off... any ideas?

 

uhhhhhh. three bars right?

 

yeah make sure your engine is fully warm, also does it shut off completely or just hit a brick wall when vtec tries to engage?

 

yeah, the engine is warmed up and it completely shuts off. kinda scares me. it only happened after i installed my dc stainless steal header.

 

any other input wold be helpful thans

 

has your engine wiring harness been messed with? install of a vafc?

state mods on the car, when the problem started, etc etc etc

problem started when header was installed, only mods are intake, header and throttle body.
everything was fine until the header install.

 

just stating the obvious since there isn't a lot of info to work with, try installing the stock header and see what happens If the install went properly, I can't see a reason why your having issues. A wire could've been damaged in the install, a connector unplugged and not plugged back in. It could be many things.

 

I'd bet that if anything, you diconnected a cable.

 

doubtful that it's the header. perhaps theTB if anything at all due to the TPS sensor, IIRC on the S. Not sure how adjustable it is, but it must be tuned correctly.

Can you describe the scenario a bit more? Going at X speed, downshift to 1st... then what?

Do you blip the throttle at all?

 

Do you have a CEL? You might be in limp mode

sorry, i'll try to be a little more detailed.

when the intake and TB was installed NP's.
after the header install, installed by Honda,
the engine will gradually shut itself off when i hit vtec.

it isn't always downshifting to first at any speed that does it. sometimes i just launch it in first, (full throttle after the initial wheel spin, and when vtec comes along, the rpms start moving backwards. hope thats detailed enough

perhaps the header is leaking? did you put the header gasket on with it?

so your dealer installed the header? if so, have you asked them why you're having problems?

 

well if it helps, i pmed him the same question, he said it's not the header install and if he wants them to look at it they'll go head and charge him up the ***. in my own words anyway
