I have mk3 golf 1.4 97 and its really bad on petrol and tickover bad went warm I have had new throttle body temp sensor ht leads plugs air filter and I got relay 167 and 30 but mine didn't have relay 30 ? And it's still bad ? Pls help

you're omitting quite a bit of information here.... and no need to open 2 threads in different section... many here read both.
which engine code or at least how many horse power?
have you (had) fault codes checked?
did you get tb alignment done??
does it run normal when warm?
revs to 6k or only about 5k2?
not all engines got relay 30.
-
Sorry for post.
It runs better went cold and it rev ok. Had it plug in and it come up with idc so had new throttle body it's bit better not lot. It's just really bad on petrol.
-
I will have to see what engine code is tomorrow in the light. Think it's 60hp
-
idc error, ok what is the proper fault code from vcds?
1.4 60hp 97 probably aex...
does it idle normally? a bit higher when cold, then going down to 700-800?
any juddering happening?
-
Does just that mate and some times drop down low ?
-
does just what? :x
idle normal or erratic?
if it idles erratic have you properly cleaned TB and got it adapted with VCDS?
-
I got the car about 4 weeks ago i put £20 in petrol and got 64 miles. on the driver home i see the tickover was dropping really low went coming to stop and was running bit raff .it was plug in to vag.com and the only thing come was the idle controll value so put new throttle body on made it bit better so I went done the plugs ht leads temp sensor relay 167 mine don't have relay 30? And the sensor on the side of the inlet and its still the same and doing loads of petrol. I was told it didn't need to be plug to have tickover reset ?

putting xx£ in and counting miles is not really the most scientific way to check your fuel consumption, especially with a mk3 fuel gauge. fill up completely and mark mileage... then drive until it's fairly empty and fill up. from that calculate your l/km or l/mi.
who told you the tb doesn't need adaptation? if it is a 60hp from 97 you will need adapt it. and no disconnecting the battery is not a tba... also where did you get that 'new' throttle from? could be having broken gears in idle stabilisation as well.
yours doesnt have a relay 30 cos it doesn't need one.
would suggest a full diagnosis with vcds - that's not just checking fault codes but also if all parameters the engine gets make sense, i.e. temperatures from all temp senders, voltages from lambda,.....

I was told by the garage that the mk3 don't need to be reset its the mk4 and up tbh i dont think they know what i was going on about. Throttle body was from vw. The bloke I got the car from said the lamba sensor was new. I did fill it right up and got 210 miles. Think the best thing to do is get it plug in again some where else. Thanks for the help mate. Just need to sort out the petrol I got the 1.4 so it was good on petrol it's costing me boom to run I might as well got vr6 lol
-
my 1.4 used to average 200 miles per tank.
and mine ran fine, as far as i know. i didnt ever have it plugged in and read, but it never had idle issues or anything like that.
also got to think about stuff like stuck brakes and things. the rear brake cylinder was completely gone on mine which didnt help.

210 miles to a full tank - I get more than that (well more) when i drove only 3 miles to work and back for a month during winter! and that's in my 1.8 estate.... on a 1.4 you should manage 40mpg fairly easily unless you're only doing short trips round town.
Even if it got a new lambda doesn't mean it's working correctly, could be wrong part or as simple as a wire is broken and ecu is not getting a correct signal.
go on google and search for vdcs map from vwaudiforum.... ;) sure there must be someone in kent with vcds that can do a proper log while you're driving... that will tell you a lot more than fault codes (mk3's are early OBD cars and not very good in reporting faults precisely).
-
200 miles per tank is awfull i atleast get 300 miles with a 2 litre i know those single point injection engine was a amazing idea to replace a carb but multi point just slammed it into the ground with being more efficient the only good thing about single point injection is that it keeps the throttle body clean i dont think you can align a throttle body with vagcom as it dosent have a stepper motor on the tb it would only be a idle setting if you could align it like the agu mk4 engine uses the alignment for idle but the rest is cable

:huh:
procedure for aex (if you really got an aex) is to clear fault codes (adaptation does not work without)
but before that would clean the TB and check if any tubing is brittle and/or broken, brake servo vacuum lines for example
then with vcds or registered vcds lite (dunno if you can do this with old shareware vagcom):
go to 01 - engine ecu
go to 10 - adaptation
go to 00 - delete values
go to 06 - back
go to 04 - basic setting
go to 98 - throttle body
that should solve the issue if it is tb related.
