when vtec kicks rpm's jumb up until 9 rpm or more!

[Ninju]

Am a proud owner of a del sol sir.lately i had some problems with it.my rpm's gone crazy,my car was swiching off while i was driving,and there were a lot of stall problems.i had some problems like that before and when i changed the distributor coil everything was fine until now.so i desided to change the whole distributor.now everything works fine except one thing.when vtec kicks in my rpm's go crazy!it jumbs from 6-7 rpm to 9-9,5.when i change gear it goes to the right rpm like 5 and when vtec kicks the same shit is happening.any idea what might be?thanks

any aftermarket add ons (msd ignition) (super afc)
Check your connection at your distributor plug, might be slightly loose

[Ninju]

the whole distributor is aftermarket but brand new.i recently put a new set of spark wires (obx).i will check this in a few hours.hope that's the problem...

factory aftermarket, or msd
I don't think its the spark plug wires
But the plug that connects the distributor to the engine harness (the one you unplugged to install the new distributor)
sorry for the confusion

[Ninju]

i hope is that simple.i apriciate your help.but why hat happens only when the vtec kicks?

[yellowrexsi]

Not sure, but the tach signal comes from the distributor (no other place), so I would start there
Also check your grounds.............there should be one on the valve cover, and one by the tranny. Honda's act funny when they aren't grounded good.



Wiring problems suck, so I feel your pain. Most the time they are solved by something extremely simple that was overlooked

[Ninju]

i will check the things you say and i will let you know.yeah wiring problems are a big pain man..and most time the problem is untraceable,but i only hope is something simple.i will let you know.thanks again

Was yr clutch in when u reached vtec rpm? If it was then rpm jump is normal.It will bounce for some seconds and come back to normal

[Ninju]

no the clutch wasn't in.problem solved today!the problem came from my NEW distributor.i opened the distributor cap,and there are 3 wires connected with fuses.so these fuses were very loose,i tighten them and everything works fine!Non ORIGINAL accesories (like my distributor) SUCK!thank for your help guys

[yellowrexsi]
