    A little help please

    that port is what the computer opens and closes to pass air to control the turbo boost. It is just about the most important "port" underneath your hood. I have had owners come to me with blown head gaskets and guess what ? someone replaced the filter with a rubber block off plug--yikes! I have...

    Rough idle when engine cold

    my experience has shown me that if the cam sensor is 180 out the problem you describe will be likely and will go away when the engine warms up. after you try all the above things give this a try. i give it a good chance of fixing the problem.

    Dual pump wiring

    the trigger signal for the second relay should be sourced from the hob switch you do not want the high current to pass through the hobb switch as it will cause early failure as for the source of power for the second pump you can source it from the alternator or you can use the same power...

    84 T-Type wont go

    if your pump can produce 90 psi with the line pinched forget the electrical issue. Doing that puts more of a current demand on that pump than anything your hot air motor can ever do that alone is proof that your "hot wire" and the ground to the pump is more than adequate when the engine is...

    to those of us that know and understand the workings of the PM and can easily maintain them your comment makes as much sense as putting a carburetor on your car if you have turbo or injector offense intended but the PM is not a complicated device but any sufficiently...

    My 8 month HORROR story. What would you do?

    note to Ron Mooney your phone text implying that I am hiding something related to your lifters is rather crude. That I am "trying to think up a good lie" to explain why your lifters were not on your bill. Your engine has a flat tappet cam and most know that flat tappet cams don't cost nearly as...

    Best starter.

    I agree that the lightweight starters are really a good idea for our cars and I put a lot of them on customers cars. The light weight is a reason alone but you might be surprised to find that it probably doesn't spin the motor nearly as fast as the original heavy starter did. Several years ago...

    Coil Pack Test Not Working.

    i realize that the method of of testing the coil pack with an ohmeter is mentioned in the GM manual. I can't imagine how that slipped into the book. That method is totally useless and will tell you nothing useful. You might as well get a bathroom scale and test the coils for weight ! The most...

    My 8 month HORROR story. What would you do?

    Since Ron and his friend were sure the problem was a "rod knock" I started with a check of the rod bearings. Rods will make a knocking sound when the bearings or big end of the connecting rod become damaged or beat out of shape. This increases the clearance from the rod journal and causes the...
