Well i first posted this on h-t and didnt get any help so here is my next stop.

The car: 00 si with just some boltons.

The problems: Check Engine light has been on for the last 2-3 months i took it to autozone and had them check it, and all it was, was black boxs, and he said it was a "relay" when it does that. Well the other day i was driving and they were repaving + dark + drop off...lets just say it was harsh. So i look at my cluster and i knotice that my spedo isnt working i checked to see if i could see any plugs loose ect and couldnt find it. Ok and now for the most recent i was driving my car the other day and my rpm guage and radio stopped working complely the next day i start it everything works except now the rpm guage will just stop working completely at random times and wont work again untill i restart my car.

ALso i just started the car up and drove it up the road and its blowing white smoke pretty bad so im going to see if its a hg or ig, do you all reccomend i go ahead and do a compression test?

Now i dont know for sure if anything is a cause of the other but a buddie of mine said its prolly the relay thats bad fucking everything up.

Any help is greatly appreciated
