one of our company trucks (the owners) is acting up

It was leaking water around the driver side head and intake manifold.

We took them off and had them pressure checked and they replaced the head with new seals and everything.

We put everything back on and it started smoking like a malley engine. Pure White smoke out of the exhaust.

I drove it down the road and back and it had a huge miss in it, we replaced the plugs and wires and fixed the temperature sending sensor that was broke off at the shop that checked the head and the miss cleared up.

Now it does not have any load end during the first couple gears it will spit and sputter and won't want to do anything till you get it up past 55mph then the top end curve of the rpms smooth out and it runs fine.

I tryed clearing the codes after we fixed the sensor but they wouldn't clear by pulling the battery terminal or taking out the fuses for the ecm.

I guess this will be a dealership visit, but we still would like to know what anyone else thinks..

I guess after 190K miles you can't expect much.

Is it still smoking? Sounds like the head gasket is still leaking. possibly a bad head. Did have the head checked the see if it is straight. White smoke usually means it burning antifreeze. Good luck!

You have to have a dealership or repair shop reset the computer. You probably have a reoccuring error code that will show up repeatedly after unhooking the battery and clearing the codes.

When I pulled my distributor to replace the intake manifold gasket the computer lost its relationship between the distributor and cam. The computer kept trying to re-time the engine at hiway speeds. We could unhook the battery and clear the code but until the computer was reprogrammed with the actual position of the distributor it would always think that there was a problem and throw out an error code.
