Hello i'm new to HT but i've been reading alot. I just bought a 94 red ls and just these passed few days i got a CEL. So i read up on how to cheak it and i'm getting the 6 ECT - water temperature sensor. I bought the sensor but dont' know exsactly how to replace it ? And the ls doesn't seam to be performing at its peak performance on the power band. From take off to around 4k is good but slowly dies down from there. Any ideas? I replaced the spark plugs and i got some of that power back but its not quite there. plz no negitave feed back
