rewind to about a year ago. the car sat all winter 09-10 outside covered with no engine. when i got the new motor in the car, the coolant temp gauge was off by about 60* but i could watch water temp on my interceptor, and with an os rad and 2 aux fans, coolant tem is not an issue. i decided to try to fix it, and after replacing the sensor 2x, checking the wiring all the way up to the ip cluster, and when all else failed, i ran jumper wires up to the ip and still 60* off. whatever *** it.

fastforward to last thursday. drive to school and when i get there gas gauge is on E and the light is on. ok 250miles is about right, ill get gas after class. get out of class, and the gas gauge now reads 3/4, wtf. get gas, and it take 15 gallons so i know the gauge is wrong, but after i filled it up the needled was pegged on F. I kept an eye on the trip for the next 100 or so miles and the gauge drops to 3/4 and sits there. great.

today i decided to fix the gauge, probably a bad sending unit. that was my though anyways. upon testing, the resistance coming out of the sending unit is spot on when checked at the access panel. i noticed something strange today though. the gauge will function properly with the car in park but as soon as i put in in drive, the gauge goes straight up to 3/4, and then as soon as i put i back into park, it goes down to where it should be. so after all my tests, the systems checks out good, and the next step in the repair procedure it to replace the ip.

so my question, who has had an ip failure and what did it do. i belive that both my coolant and gas gauges are ***ed and the only fix will be a new cluster. has anybody else had similar issues?
