Ok, so.. you've got an '87.

I don't know a thing about your setup.

Are you using an HKS Harness? If not did you hardwire it? Did you use resistors? Did you unplug the stock AFM? Do you have the right ROM (440cc = SUP011N / 550 = SUP009B)? Are your sensors plugged in to the main box? Does changing the idle knob actually change your idle?

When my car starts from cold, it's finicky and obnoxious for the first 45secs or so. I just finished my VPC Hardwire with the factory 440 ROM.

using the correct hks wire harness, removed stock afm, used the right ROM (440), sensors are plugged to they're corresponding harness, idle knob did change the idel but not by much, noticable difference but still not drivable.

Any trouble codes? You may need to play with the other knobs also.

 

[empera]

tried playin with knobs, no engine codes...

Do you have an S-AFC? What does the Hertz say and does it fluctuate?

 

[empera]

nope no safc, yet

 

[88targarose]

I'd say make sure you don't have broken wires somewhere. Other than that, I'd say you need an AFC to confirm that the Hz are moving like they should or you've got a bad ROM/bad VPC.

appearantly i have a bad pressure sensor. Had someone check the sensor on they're setup and got the same results.
