I have a 2000 4.6 P38 have had the heads changed, spark plugs, wires and "coil packs" (if that is the right term). All that was done within the last 10k to 15k Spark Plugs prob last 5k. I haven't had any problem with the motor but took it in to have the rear air springs replaced yesterday. When I picked the car up today the check engine light came on. He put the computer on it and said it had a misfire on cylinder 4. Asked him what it could be and he said worst case it could be leaking coolant into the cylinder and needs a new motor. He said that cylinder is common for that problem. He asked me if I ever over heated it and I said no. I bought it with 70k miles and it has 101k now. Worst thing that happened was I busted a radiator hose at about 75k miles but I was less than a block from my house and I never saw the temp gauge get into the red. He reset the light and I drove it for another 20 or so miles and it came back on again. I will take it back tomorrow to have him pull the plug but is that something I should worry myself about? Would they have notices that when they changed the heads?

Thanks
