RyanRs Posted June 25, 2005 Report Share Posted June 25, 2005 Hi, my escort 1.8 GTi........ is a 1997, 54,000 miles and well looked after (not frashed..) Now, i have modded the engine.. K&N, 130ps Cams, 2ltr throttlebody, Decat, ss magnex exaust, different gearbox, magnacore leads, NGK platium plugs (brand new)... My problem is... my car seems to be geting 24 miles out of a FIVER of petrol!! I dont understand, thats as bad as a 4ltr v8 guzzler!! My plugs & leads are new and good, i got no missfires etc so timing must be good. Why is it drinking sooo much! Maby i need a superchip to sort this? as it has a fair few mods but on the standard ECU, wich on ford escorts, cannot be adjusted (air/fuel etc) it does tick over slightly lumpy, and takes about 20min to properly warm up.. It pulls with NO power for the 1st 20 min and if you take your foot off the accelerator then immediatly back on, it does a quiet backfire out the exaust, then after the 20min warmup, it like all of a sudden it goes like a supercharger has just been strapped to it and flys! why!! and sometimes i find if i dip the clutch after booting it, the revs get stuck at 2000 rpm for bout 10 sec, before dying down. Superchip or dodgy injector? or something else!? Any ideas? Ry :D Quote Link to comment Share on other sites More sharing options...
Dai the Socket Posted June 25, 2005 Report Share Posted June 25, 2005 I'm having car trouble! Can't get a quote. It isn't that unreasonable is it? Even 'confused.com' cant get me one: * 1989 VW Golf Gti (Mk2) * Alloys * Tints * 1.8L Petrol * Pass plus * 0 years No-Claims. And I'm 17. Haha. I got one. But it was £4580 Annually :D Quote Link to comment Share on other sites More sharing options...
hazzyhaslam Posted June 25, 2005 Report Share Posted June 25, 2005 speed idle control valve sounds like :D Quote Link to comment Share on other sites More sharing options...
David Posted June 26, 2005 Report Share Posted June 26, 2005 Is there some fuel coming out the exhaust with a thick blue smoke? Engine might be too rich?? Quote Link to comment Share on other sites More sharing options...

trials_pimp Posted June 26, 2005 Report Share Posted June 26, 2005 Ah for the Escort. They suffer from a few things. IAC Valves sticking, and the revs hold up. They suffer from sticking valves, bit this will give you a complete lack of power. The reason your fuel consumption has gone up, is because you have modded it. The K&N lets more air in, so the EEC V PCM is allowing more fuel for the air thats going in. Same with the throttle bodies and the cams, they are desinged for a bigger engine, so your PCm is letting more fuel in. Also. what box have you fitted? if its from a smaller engined car, you will have better acceleration, but a lower top speed, so you will need to gun it to get to speed you used to on the older box. This is the scarifice we make for playing around with cars, you cant have it all, choose, ecconomy and reliability, of perfomance. PS - EEC V = Electronic engine control 5 PCM = Powertrain contole module IAC = Idle air control Quote Link to comment Share on other sites More sharing options...
the666ers Posted June 26, 2005 Report Share Posted June 26, 2005 Sorry mate but you will never get reasonably insured on anything wit gti written on it or over 1400cc till you are at least 20. Most insurers won't touch you with a barge pole, especially on a mk2 gti! Quote Link to comment Share on other sites More sharing options...

PS - EEC V = Electronic engine control 5 PCM = Powertrain contole module IAC = Idle air control ← IAC valve sounds like the possible fault. i no that some of the mk7 escorts have a fault with the ECU, to which Superchips daughter board fixes -along with all the usuall stuff it does ie, remapping the fuel ect. Thing is, i understand about performance VS economy, but i have owned a 1.6 CVH escort on webber 45 DCOE's, with kent cam, ported and skimmed head, 1.4 gearbox, and al the usual exaust, filter etc, and it still got atleast 32 - 35miles to a fiver! And my friends 300BHP MR2 2ltr turbo also does better!?! Now, i did strap a flamer kit to the exaust once (i make these myself, -i make the module part before any of you say 'thats easy, anyone can do that!') and, it Shuldnt flame at all, being a new zetec engine. but if you redline it and then let the revs drop, a bright blue flame would come out and burn for a couple of seconds..? this could be due to being too rich you? i dont get any smoke come out at all. the Gbox is basically a std zetec box, but recon'd with a 1.2 feista zetec main drive(takes the whole ratio down to the same as a xr3i 1.6 box ratio) and a RST LSD fitted. so, it is closer ratio but where the car has quite a bit of poke, i can skip gears quite alot to avoid high revs, ie 1 - 3 - 5 without going over 2000ish revs. i can cruse about in 5th down to about 20mph. so i wouldnt say the box is too much the problem Edited June 26, 2005 by RyanRs Quote Link to comment Share on other sites More sharing options...
colly Posted June 26, 2005 Report Share Posted June 26, 2005 you got the throttle bodies, on a rolling road to get the engine management power map correct? Quote Link to comment Share on other sites More sharing options...
RyanRs Posted June 26, 2005 Author Report Share Posted June 26, 2005 you got the throttle bodies, on a rolling road to get the engine management power map correct? ← well, its only a 2ltr mondeo zetec throttlebody. its the same as the standard one in design, just with a bigger bore and butterfly. i needed this for the sake of the cams, as the 130 PS cams come off a 1997 xr3i zetec, which has the same engine as mine, just with 15BHP more (mine has 115bhp std) - the difference is the cams, throttlebody and ECU. thing is the ford zetec ECU isnt programmable. so if i took it to a RR, its very limited on what they can do. so i need to get a superchips fitted to the ECU 1st before they can play around with it.
