Lookin' good

Sorry about the MAP sensor confusion, I did my swap so long ago, that I have forgotten the little details

Well so here it is. I just put on some MSD wires and reset the ecu once again. Didn't figure it would help at all, but to my suprise, i could notice a difference. Not only that but when i checked the codes again, none but code 21 and 22 flashed (the 2 Vtec codes, Pressure switch and solenoid i think).... The idle still bounces about 30% of the time so i know the TPS needs adjusted but i just couldnt seem to get a reading off the multimeter (tried all the sensitivities).... I'll try it again tomorrow with a better place to work...

The car still hesistates but not nearly as bad and it doesnt seem like a "Barrier" anymore... Doesn't seem like it is as dependant on the throttle anymore as much as what RPM im at. Weird.

All in all today was a good day, i managed to eliminate most of my engine codes but i still dont have Vtec... I'm sorta worried because i just got this motor in in december and i havent had Vtec engage one time... I'm really not even sure if the solenoid is good at all.

Any Suggestions?

Thanks fellas

Adjusted the TPS for WOT. Closed reading is .41V and the WOT is 4.51V. Car still has an oscillating idle but now it is barely driveable below 2000 rpm. Bounces around like you are just dumping the clutch over and over, so im going to adjust it so that when closed it is exactly .5V and to hell with what it is at WOT.

This is getting excessively annoying. Also, there is only one wire coming from my Vtec solenoid (green w/yellow stripe) No ground or pressure switch... How does one go about wiring them?
