Hi I’m keen to hear others thoughts on this to help me work out what I need to look at. GT 3f fuel pump primes and car runs fine once started. Just when cold and been sat longer than a day it doesn’t start after the first prime, normally 3 primes makes it start first time. I've tested fuel pressure during the cold start, at idle and with vac off the FPR and it’s getting plenty pressure. It’s like it’s getting insufficient fuel after one prime. But then after second attempt it catches and runs fine. Fuel filter is 2 years old. I have a spare FPR but before I sta

Hi, When starting the engine from cold and even once it’s warm the car has bad throttle response. The revs die off under throttle and along with this the idle is slightly higher than normal about 1000-1100. The odd thing is, when turning the ignition off/then restarting the engine the problem goes away and it runs without any issues at all. It started out intermittently and now is doing it all the time from cold. I have today checked all the earths and cleaned and lubed them. I have tested the ecu to sensor wiring for continuity and the temp plug, TPS, AFM are all okay. So is there a

seen some older threads where folk have converted a 3f into a 1600cc with a AEE engine , is there any alternate codes that i could look for ?

3F GT idling high occasionally and flat spot in revs
Bawbag posted a topic in Engine, Transmission and Exhaust
Hi I’ve had a read of the FAQ and found the diagnostic page useful over the years, but now asking for some advice if anyone else has had the same. The engine has had good quality ignition parts including a genuine VW blue temp sensor about a year ago. The symptoms have been ongoing for longer than this so they aren’t stopping the car from driving but I’m keen to fix them. 1. The idle creeps up to about 1300 or so occasionally, and comes back down eventually. I think this is only when the engine is up to temperature. I’ve tried unplugging the blue temp sensor following the normal proce -
some info on improving your mk2f GT, not a comprehensive post so feel free to add you tips these are the quick power gains • high lift cam 264 / 268 / 270 - the biggest gain is made here. dont forget new tappets • 4 branch manifold and exhaust system - dont go to large or it will cost you power • bigger injectors • better air filter • chipped ecu those probably account for 95% of the gain you can get from the engine the next lot help to pull a few extra horses out for those who really want to put the work in: • skimmed head / port matched with i

engine codes Help!! Is this my engine code or am I a muppet?
Jimbo247 posted a topic in Engine, Transmission and Exhaust
So hi! First post on here hoping someone can help Bought a 91 polo gt last year for a bargain and due to house move and job change amongst other things I haven't had a chance to give it a good going over. I might be being an idiot but I might be finding out why it was a bargain.. If this is actually the engine code. Started looking it over today and wanted to check it was actually a 3f. did some searching to find the code location and found a post saying "just where the block meets the head above the alternator mount" so looked there and found this. I have found ot -
Cheaper insurance premium after fitting larger engine (3F to ABD?)
oldtech posted a topic in Paperwork
I can remember being told by my insurers that in the case of an engine swap declaration, the new price is calulated according to the donor car. So my question is: if I were to swap say from a 1.3 3F GT to a 1.4 ABD, might the insurance decrease as the 1.4 Golf is presumably cheaper to insure than a GT (don't know if it is actually cheaper - just in theory)? Or, is there a 'tax' added for the extra perceived risk of an engine conversion? Has anybody ended up with cheaper insurance despite using a larger engine - say specifically a 3F to an ABD? Or did it increase? -
my 3f conversion failed the mot today , 10% co at 10% its running fairly normal , sounds and drives "okay" so i gets home and mess with the afm , i can get it lower towards a pass , but it just hates it a pops and bangs and really doesnt like it all all service parts new /good , o2 unplugged,temp sender looks good on scanner , tried another afm , messed with ign timing etc checked all i can think off , cant really get my head round why it wants to run so rich and wont /struggles near normal readings

There are three types of multipoint injection engine, the G40 is quite easy to spot. This guide is to help you spot a NZ from a GT This is a GT engine (some light modding) This is a NZ engine The NZ is a multipoint version of the AAV engine which was later developed into the GT (3F). • The NZ has the same camshaft as the AAV and was meant to produce the same 55BHP but because of the improved air and fuelling some NZ produce 60+ • The NZ throttle body has a throttle open sensor not a position sensor like the GT • The NZ has the same gearbox as the AAV • The NZ has

Got a polo gt coupe in black, really condition bar the hole in the driver sill / floorpan and the 2 inch one in the passenger sill. Interior is almost mint, driver seat has an open seem on top corner. Pretty much std with a single wiper conversion, home brew mount Not had it to long so not given it a full going over, did notice the rad is cracked and the member it sits on is bent so its tapped an curb? Waiting on photobucket to show my pics Really would be nice for it to go whole as its a hardtop gt in black and pretty good condition

Hi everybody, I am collecting parts to build a 1.4 abd engine with 3f upgrades (intake, wire loom, injectors, ecu and camshaft) Trying to find a 3f throttle body, which is pretty hard to do. Am planning to put a 268 camshaft and 180 ml injectors in, in the future. So a slighty bigger diametre throttle body might come in handy. So are there any oem throttle bodys that anybody knows of, that might be a upgrade to the 3f one?
