Idle problem with P39 ECU!?

[Alex EX]

I just got the P39, put it in, let the car run for 10 mins and after about 7-8 mins the tach started jumping from 1k-1500k back and forth non stop, then I drove it and it did the same thing... I didn't have this problem witht he PT3, I tried adjusting the circular vacuum thingie on the top, didn't help. What else should I do?

[AFAccord]

Make sure everything that is connected to the ecu is tight. Because when I was trying to take out mine, a wire became loose when I put it in and the rpms went crazy when I was driving.

[Alex EX]

Which wire was it? On the ECU or that black one going accross the ECU on top?

[AFAccord]

It was on the bottom. The wire closest to the passanger door.

How did you fix it?

[AFAccord]

I just pushed it in and made sure it was securely in there..Then I took it for a test drive and the rpms were fine.

[Alex EX]

I took off the battery cables overnight to reset it... Maybe thats the problem?

[Alex EX]

None of that worked =( what else should I check?
