GrlNexDor6 04-01-2009, 07:20 PM Does anyone know what it means if your car stalls/sputters when you go above 4000 RPMS? It's a 5 speed, 4 cylinder EX. Whenever it happens, my check engine light comes on. The code says V-Tech malfunction, but that seems pretty broad. Can anyone shed some light? Aviography 04-01-2009, 07:24 PM One possibility is that there have been containmanent trapped by an fine mesh screen in the VTEC solenoid oil inlet, and it is preventing the higher lift cam lobe from engaging. Not sure about your V-6, but my old Integra GSR was fairly easy to get to the the solenoid valve to check the mesh screen. BTW, it's VTEC, not V-Tech, which is a wireless phone product! :D Bruce Hawkins 04-03-2009, 05:25 PM Hi, When I purchased my Accord 2 Years ago, I had a P1259? VTEC, Oil pressure switch problem... Anyway. It was apparently already, repaired or replaced. Because after I reset the code, using a code reader (Or Fuse-13, passengers side, is the same - I think), it went a way, and never came back (disconnecting the battery makes it go a way TEMPORARILY, till you hit 4K, again - DOS NOT MAKE IT GO A WAY). There are TSB's for this. But; First check the oil level (maybe change the oil, if not done recently (make sure its 5W-20 or whatever is correct for your car (Oil change places, regulatory use the wrong oil), check that the connector is connected, and the wire to it, looks OK. If the oil pan is dented, or as already stated, crud in the screen, can cause this problem, as well ... Id, reset the ECU (erase the code) and change the oil, again; Using the correct oil. Do it your self, or go to somewhere else, see what happens...

She has an I-4 :thmsup:. If you've recently had an oil change or need one that's probably the culprit, otherwise just changing your oil out of the blue won't do you any good. If you're mechanically inclined I would recommend taking the vtec solenoid off and cleaning it with a solvent. However, don't try and remove the filter unless you have to. | ||
