Question: hi, i have a 1994 ford escort with the 1.6 zetec engine and the starter motor at the front of the engine. it has 192000 miles on it and is blowing abit of blue smoke, so i thought it would be more cost effective to change it. is it possible that a 1998 1.6 zetec with the starter motor at the rear would fit and do you know what i would need to change over? by the way my current engine has efi stamped on the inlet manifold whereas the one i might be getting has the revised induction.
Answer: Hi.. You change something that doesn't need changing at your peril! I didn't think there were many chnges made, but sometimes, it isn't obvious. Have you considered getting your old engine rebuilt?

Question: HI ALAN, I HAVE A CRANK SHAFT POSITION SENSOR ERROR ON MY VECTRA. WHEN I AM DRIVING THE RPM NEEDLE DROPS AND THE MANAGEMENT LIGHT COMES ON, BUT THE CAR WILL DRIVE ALONG FINE. BUT WHEN I STOP AND TURN THE CAR OFF AND GO TO START IT AGAIN I HAVE TO TURN IT OVER FOR A FEW SECONDS BEFORE IT STARTS AND THE MANAGEMENT LIGHT STAYS ON. I DID A FAULT CODE CHECK AND IT IS TELLING ME THAT I HAVE A CRANK SHAFT POSITION SENSOR ERROR. I AM GOING TO FIT A NEW SENSOR, AND I WANT TO KNOW DO I HAVE TO CLEAR THE ERROR BEFORE I FIT NEW SENSOR AND IF SO HOW DO I DO THIS. APPRECIATE YOU\'R INPUT INTO THIS. MANY THANKS JOHN MC MAHON.
Answer: Hello John - It's a good idea to have it done by a dealer or tuner. If nothing else, they can confirm the diagnosis, and do it again if the light comes back on. ( They often do! )

Question: hi alan, great site. i own an audi 80 2l 16v and have noticed that its pinking under load. i have had a good look around the car and whilst doing an oil change i have noticed a sensor hanging down. i doesn\'t look like its a internal sensor because it is mounted on a bracket. the sensor has two wires going to it with spade type connectors on it and the sensor itself is short with what looks like a brass round plate at the base. could this have anything to do with the problem or is this maybe just some kind of under bonnettemp sensor for the cooling fans. any help would be much appreciated as i cant find a repair manual for this model,thanks for your time richard.
Answer: Hi.. That sounds like a knock sensor, and is very likely the reason why it's pinking. It should be bolted to the block. The object is to detect knock, then control the timing accordingly.

Question: hi alan, i have an rs turbo series 2. whilst driving the car cut out and rolled to a stop and wouldnt fire up. i changed the fuel relay as advised but it kept cutting out in mid drive also blowbacking. i changed the distributer body and ignition coil as advised again, now i tick over too fast blow black smoke for a while and when i drive and then turn the engine off it wont fire back up for 10 minutes, like the battery is flat. had the starter motor rewired but the car still plays up. im lost, need the car tuned but i cant risk driving at the moment
Answer: Hi..It sounds like it's running rich, check the coolant sensor multi plug is connected up properly under the inlet manifold. It's very easy to mix these up, we see that one all the time. The starters are lousy on these cars, and frequently fail when hot. We use new starters, rather than ones that have been re-conned ten times already.

Question: hi, i've just bought a power boost valve for my corsa due to a fuel pressure problem around 3 - 4 thousand revs, which was discovered when i took it on a rolling road. i just want to know at what pressure it should be set at?
Answer: 42 psi at idle should be fine, assuming it's a multi point injection.
