Question: hi alan i have a standard t25 escort cosworth and when you lift off the accellerator its as if something pulls the car back then lets go ie as if it had an elastic band attached so it slows up then the band snaps and it coasts on easily. strange description i know but best way to describe it.it only does it occasionally and sometimes worse than others thanks justin.
Answer: It sounds like the kind of surge than can occur when boost pressure is raised, usually confined to those with mass air meters. The Escort doesn't have one, so I'm going to suggest checking for air leaks, possibly to the map sensor, or maybe a throttle sensor fault or mal-adjustment.

Question: Hi Alan I have a 1995 Hyundai pony 1.5 X2 model 65000 miles. When i try to start the car it fails on first attempt but fires up on second, why is this? I think it may be something electrical. Please can you help. Many Thanks Cheryl
Answer: Hello Cheryl - Assuming it runs ok when it does start, the chances are there really isn't much wrong with it that's worth fixing. You could try checking the plugs and leads out, apart from that, it may be due to poor valve stem seals if it smokes on start up, or maybe a leaky injector. My attitude with older cars is, if it's doing what you need it to do without too much bother, then it's probably best left as it is, apart from normal servicing.

Question: can i have a supercharger fitted to my st170
Answer: I haven't seen a kit yet, but I bet the price will be similar. The difficuly is, the engine isn't suitable for forced induction without rebuilding it with lower compression, and sorting out the engine management. I see so many kits supposedly designed for standard engines, when they are crap unless you eventually sort it out properly. To my mind, if you can't afford to do it right, don't even attempt it!

Question: Can i have a turbo fitted to my st170
Answer: Possible, but very expensive. I'd say ?5000 to get it right. Better off buying the RS Focus.
