Hey guy, I could really use some advice. I just had a stock 98' 4.6 gt engine installed in my 96' gt. Also had a new fueal pump installed. Well its been a couple weeks and the car the car started to over heat like almost the first day, but it over heated with the old engine. I asked the mechanic to check the water pump on the replacment engine and he said it looked fine. So I figured it was the radiator. So I installed a new radiator but it still runs warm in traffic. the needle sits on the "A" but drops down to the m almost once we get moving again.
But the next problem was the car started running bad, spitting and sputtering, would have to down shift just to accelerate anything under 2500 rpm. So I figured new plugs and bought them $10 a peice bosh plugs. Didnt fix it. So I went down to Discount auto and the hooked it up to there dianostic machine and here is what it says:
ENGINE COOLANT TEMP
CIRCUT HIGH INPUT
SYSTEM TOO RICH
So im going to go pick up a new set of plug wires and hopfully this will fix the missfiring, but my question is if that does fix it, would it also fix the "system to rich" error.
And any ideas what the circut high input on the engine coolant could be. I also have a new thermostat.
I appricate any help guys, I live in south florida
and have been driving 100 miles a day for 3 days with it like this. Any chance the cylinder #6 plug is ruined. its one of the bosch irodium $10 plugs....im on a super tight budget....again...appricate any input.
o/2 sensor is reading to rich
number 6 cylinder is miss firing
