AJC 0 Posted October 10, 2006 Basically, im new to Pugs, apart form my 106 gti form 3 years ago i do have an escort Cosworth but im a bit bufty, so not wanting to use it over winter, soo.... i bought a 205 gti, now the car handles awesome, it is standard btw, but it doesnt seem to pull as well throught the gears, and is a tad lumpy and gutless, i think it maybe the Air flow meter, but dont want to blow 130 quid on one to find out it aint any ideas people?

welshpug 1,626 Posted October 10, 2006 check the ignition timing and vac advance, a good service may be on the cards as well as a cambelt if you dont know when they were done last. and afm will affect the car in a more drastic way than just being a bit flat.

smckeown 1 Posted October 10, 2006 and afm will affect the car in a more drastic way than just being a bit flat. Not in my experiance, it can mean the car runs lean. Find a local garage with a gas analyser and knows how to adjust pug AFMs. I experienced very good results after mine was adjusted professionally Sean Share this post Link to post Share on other sites
AJC 0 Posted October 11, 2006 cheers, the car is over fuelling as im going throught petrol like its going out of fashion Share this post Link to post Share on other sites
welshpug 1,626 Posted October 11, 2006 aaah, try an engine temp sensor Share this post Link to post Share on other sites
Grim.Badger 15 Posted October 12, 2006 (edited) aaah, try an engine temp sensor Try this first, it's a blue plug near the thermostat (although it's probably brown/grey like most things under a 205 bonnet ). They're £10 from people like GSF, do a search on here for the part number as GSF stock it as a BMW part. If this has gone the car will stink at idle. Once this is sorted, if it is the temp plug, change the oil (as it's likely to be contaminated by petrol) and give the car a damn good run in, then it wouldn't hurt to change the oil again to make sure you've flushed out the engine properly. If it's been really bad then you may have to change the plugs as well, although if they're new I'd have thought you'll be able to get away with keeping them. Also is it a 1.9GTi running on 95ron unleaded by any chance? Edited October 12, 2006 by Grim.Badger Share this post Link to post Share on other sites
nick 3 Posted October 12, 2006 When you say it's a bit gutless, are you comparing it to another known good 205 gti or your 400bhp cossie?!!? Nick Share this post Link to post Share on other sites
AJC 0 Posted October 12, 2006 cheers people, i will try general traffic this weekend for temp senser it is run on 95 ron yes, 1.9 gti i have not touched it since i got it, but i did noot intend on spending anything on it, but i been caught out by the 205 bug already, i love it Nick, yes it is slow compared to the cossie lol but it seems 1.1 slow Share this post Link to post Share on other sites
Grim.Badger 15 Posted October 12, 2006 (edited) cheers people, i will try general traffic this weekend for temp senser it is run on 95 ron yes, 1.9 gti i have not touched it since i got it, but i did noot intend on spending anything on it, but i been caught out by the 205 bug already, i love it Nick, yes it is slow compared to the cossie lol but it seems 1.1 slow Once the temp sensor is sorted run a couple of tanks of super unleaded (97 or preferably 99ron) through, then advance the ignition to suit superunleaded. The 1.9 feels guttless and strangled on 95ron. There could of course be other problems, for example the clutch was slipping when I first got mine which I didn't realise for a while until it started to get bad . It could even be a collection of problems as simple as a restrictive exhaust, blocked air filter, old ignition components etc. Mine stangely felt a lot better when I changed to old knackered split induction piping for some new ones, I can only assume that the old pipes were collapsing when the engine was under load, and therefore restricting flow. Also both of my pugs have needed a sort of run in period to get the best out of them because the last owners hadn't serviced them properly and both had been sat around for a while not being driven. The lumpyness could be an air leak. One of the simplest places for lots of air to get in is through one of the bolt holes in the intake manifold, such as the one that is meant to hold the oil filler cap in place; it's common for 205s to lose this bolt.

AJC 0 Posted October 12, 2006 cheers badger, it will be next weekend now, but i will get on it and see what i can do, the only problem is, it was meant to be a winter smoker, ans spend no money on it Share this post Link to post Share on other sites
AJC 0 Posted October 16, 2006 replace the engine temp sensor, no change, exhaust is next mod to try over come that as it is old n nakerewd and blowing Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted October 16, 2006 Mine was tuned for 95 when I first got it and it certainly flet flat and slow. I can't say that about it now. This would be my number one starting point... Also a lesser effect but none the less good is to get the injectors cleaned. On the two engines I've had done it makes it feel stronger at high revs. Idle mixture will probably be wrong but this is best adjusted once ignition timing has been done as can the idle speed. AFMs can be cleaned, refurbed or replaced with 2nd hand items for zero or small amounts of cash. The exhaust down pipe should be two D shaped pipes welded bck to back for the first half or so of the pipe. Cheap replacement pipes are not and can loose you power as a result. ARVIN downpipes certainly come with the split, not sure about others. 205 idle is never good even when right but 90% of cars can be improved with some tweaking...

j_turnell 134 3 Cars Posted October 16, 2006 Personally i'd check or change the following: - cam timing, worth doing the belt and tensioner anyway (also water pump) it could be out by a tooth maybe. - Ignition timing, set it for 97 ron. - replace plugs, leads, dizzy cap, arm, oil,filter, air filter. - get it on a Co machine and get the mixture set, after the service. - Replace ecu temp sensor. - check for cracked exhaust manifold. - clean all air and induction pipes including throttle body and possibly inlet. - Worth takin the SAD off and cleaning that out too for cold mornings. - check for air leaks, a search will give you the common places.

AJC 0 Posted October 17, 2006 cheers people thats a lot of things to do i dont want to spend any dosh on it lol will do what i can cheaply biggest issue at the moment is the full tnak of petrol to 180 mile:( Share this post Link to post Share on other sites
j_turnell 134 3 Cars Posted October 17, 2006 Well a good service and Co check should save you money then in the long run along with a little less right foot heh. Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted October 18, 2006 Ignition timing is free Vacuum advance unit may be bust or pipe fallen off, that is good for about 10% cghange in economy. Idle may well be rich, common 2nd hand AFM should be £10 or less and may help. Share this post Link to post Share on other sites
AJC 0 Posted October 18, 2006 cheers chaps, idle is rich, i can tell car seems lot nippier now, changed temp sensor and put 97 ron in cheers for the help Share this post Link to post Share on other sites
Rob_the_Sparky 9 Posted October 18, 2006 Right get the ignition done next (once you have got through a complete tank and re-filled) and you should really feel the difference. Rob P.S. In good tune you should get 35mpg if driven without a lead right foot. Share this post Link to post Share on other sites
