Okay guyz. I just picked up 1994 gsr and the original owner must have been a dumbass. well to start of the vtec is hooked up to a switch. When the switch is on the vtec will hit at 5k rpm. After hitting it like 2 or 3 times It will stop hitting vtec and run like a ls. It will rev high and all just wont hit vtec. i have to shut off the car and pull out the key and insert it again for it to hit vtec again and sometimes it wont even work after that. Any help would be appreciated.

Next. if i rev slowly while driving until i hit vtec, one i hit vtec it feels like the motor starts to jerk back and forth (sorta like a bogging type thing)P, but if i stop on it after i engage it pulls hard.

Also some times in low rpms if i step on the gas normal it feels like its hesitating. The car would jerk then start driving fine.

The wire that hooks up to the abs fuses is not hooked up the battery. is there anything else that that is hooked up the abs area that may be affected by it?

The car is a 94 gsr teg and the motor is a 98 gsr. How exactly can i tell if the whole harness is obd-2. I know 98 was obd2.

Thanx again guyz.
