dodgy vtec ??

pablosd

hiya
friend has a 97 sir civic, and when he goes over 5500rpm vtec kicks in then at 6000 revs kinda stops and then kicks in again, the car keeps reving but vtec disengages and engages
anybody have an idea what it could be??

Midnight_EG

What jumps straight to mind is either 1) Low oil, 2) Wiring is fxcked or 3) Vtec solenoid is faulty, may need soldering again or new wiring.

thanks i'll let him now, its funny cos it only happened there yesterday, it was sound b4 that, must be low oil i'd say or maybe the oil pressure

Midnight_EG

And, seeing as you said it kicks in at 5500, does he have a VTEC controlller in it, cos that can play up with the VTEC, best advised not to use one TBH.

Was about to say the same thing....

Midnight_EG

My guess is he wanted VTEC later, so messed around and now he basically doesnt get it, leave it at 4800 man :[

Useless otherwise.

no there is no vtec controller in it, just rsm de-limiter, it worked sound b4, and he didnt mess with it a while, the thing first happened yesterday
sorry 4got to say its 1.8 integra dc2 type r conversion

Midnight_EG

Still shouldnt be kickin in at 5500 man

Thats reserved for the K20s and whatnot ;L

pablosd

well i remeber when vtec was kicking in the rsm read 5200rpm and rev counter would say 5500, would that make any difference thou??

Midnight_EG

yeah, usually theres a major difference in readings, so really no point in having them, and id get the timing checked out too, bring it down to the VTEC specialist in the industrial estate whos name escapes me.....beside the coca cola factory

pablosd

well he only has it fitted to cut the speed limit

he texted me there he is getting the oil changed first thing 2moro, if that doesnt help i told him 2 ring up icetronix 2 get the problem looked at, they know their hondas inside out

VTEC on DC2's kicks in at 5800rpm as standard.

i thought that too, but wsnt sure

Midnight_EG

i didnt see the edit to say it was a DC2 conversion, so thats spot on :L


Still probably low on oil or the VTEC solenoid playing up

Check the oil level, then the solenoid screen, then check the solenoid, by taking the solenoid apart and pushing on it with your finger to insure it moves smoothly. Then move on to oil pressure. If all else fails check all wiring.

For what needs to be done, dont go to Icetronix, 41 euro an hour, its a waste, bring it to any garage, they'll do it, not too hard.

sorry i added it up, thought i'd made a bit of a difference :P
i let u kno whats da story after he got the oil changed....
out of curiosity, how much 4 a new vtec solenoid??

Midnight_EG

Huge difference :L

And yeah do, let us know how it works
And not quite sure, take a look round a scrapyards, or to be sure, Icetronix, for once, is the way to go :L

pablosd

got a text there, oil changed problem solved

delighted to see another healthy vtec back on the road

Midnight_EG

Happy at that now
