Subject: Astra SRI
Sender's Name:
Question: I have just had to replace my Air Flow meter on my Vauxhall Astra SRI (1800 E- reg) - I managed to get one from a breakers yard. The replacement was needed as I had managed to flood the engine with water during the recent bad weather. I no longer have any difficulty accelerating but the engine does sound lumpy when idling. Do I need to adjust the air/pet ratio? if so which way do I turn the adjuster screw and by how much - can this be done without special equipment ?
Answer: There are two types of mixture set up...one is a largeish allen screw..this is an air bleed.. you screw it in to richen. The other type has a small screw in the side..you screw that one in to richen too... . You can't beat a gas analyser to check the correct levels.

Question: Most of the time My 1998 Ford Ka is perfectly behaved and seems to idle well. However It has developed a disurbing and potentially dangerous habit. After the 10 mile drive or so as I slow down for a roundabout or junction the engine will sometimes stall leaving me with now power, brake servo or power steering. So far the engine has always restarted when I have turned the key.
Answer: There are a number of possibilities with that one!.. can only suggest a fault code read.. most good tuners should be able to do that.

Question: I own a pulsar gtir turbo, it was stolen I now have it back now but the culprits have done some damage which ment an engine stripdown in situ ,now I am putting it back together but have hit a problem I dropped a clanger, I didnt take proper note of the valve timing and have lost it completely so I am looking to you for some help it would be very much appreciated.
Answer: Ouch ! ..be very careful. I'll be honest, I have no idea without looking it up. I would say your best bet is to try and contact a specialist on these cars. It may be that there are no marks, and you need tooling to line the cams up, like you do with a Ford Zetec. There is a company called Hiteq (01942 721778), who do a lot of Jap import stuff.
 
Subject: Mk 2 Golf Gti
Sender's Name: Top Boy
Question: have a mk2 Golf Gti 8v (91)digifant and was wondering if it is still possible to get a turbo conversion from you. Also would it be compatible with the digifan models as the only conversions I have seen are early mk2's (84/85ish).
Answer: Yes, it is still possible, although you would have to come up with a lot of the pipework. Manifolds are ? 350 and turbos at ?400 . Expect around ?3000 for a full conversion.
 
Subject: Ford Orion 1.6i ghia
Sender's Name: Andrew Shears
Question: I have currently got a ford orion 1.6i ghia / f plate. I was wishing to know if i could change my engine to a 1.6 turbo instead of injection and how much it would cost??
Answer: Well it is possible, and a common conversion. I'm not sure it's a really good idea though. Personally, I would sell the Orion, and buy an RS Turbo ! Most of these conversions were done using stolen parts....and you have to change everything, engine, loom, radiator..etc
