ok i got this car about 5 months ago and when i got it, it had a dx engine with a blown head gasket, and the idle would go up and down from 1000 to 1500. at first i thought it was the map senser but i replaced that and filled it with coolent and it didnt fix it, so thinking it was the head gasket that was causing idle i put in a d16z6

now here's the problems

when i turn the car on it will idle for about 3 seconds go up to 1500 and then die, but if you hold to peddle and keep it idled until it warms up it will either idle very low (about 6500) or the idle will go up and down,


also,

a wire that went to my fuel pump relay fried and after i replaced that wire my gauges, turn signals, check engine light wont work, and odometer
BUT

everything that will work without the key on will work

ei the dome light,headlights, gauge lights, and hazards

can you guys help me??

 

can anyone help me?

 

i read from red del sol si that he is having the same problem, was it ever solved??
