Beaten down by a Nova.

[86gti]

get Kjet and a 2e.... do some head work, a cam....and some fun with shims n pumps....have fun with gtst skylines..
my 2e pops off 7g all day long..revs smooth and has enough torque to tow a tractor...

Dont be quick to dismiss a good 8v...

A local 8v is a bit of a S&%tter tho...
Oz delivered 8v were the JAP type strict imission detuned boat anchours.

Mine revs fine, you have another problem there.

Did you adjust the spring rate on the bmw afm? you need to loosen it about 8 clicks the 1.8 doesn't have the vacuum to pull it open at the normal tension.

Only thing I can think of is the O2 sensor, is it chewing through more fuel since its been sluggish? also have you tried putting the old chip back in to check that?

I loosend it and it is fine in concernes with pulling it open etc but no matter what you do to the tension it will not open more than 90% on full throttle.

I have played with everything today. The temp sender made no change.
I put back the OEM MAF and it was the same. I replaced all vacume lines, checked spark plugs and leads etc all seems good. I put back the stock chip and the car wouldnt start lol.

The problem has been there since as far back as i can remember, before all the mods. I remeber buying these mods thinking it would help the strugling.

I unpluged the O2 sensor and it had the same strugling problem but alot more violent. I also found something wierd in the wiring, one of the wiers that goes to the plug of the o2 sensor is wraped in another wire which is grounded to the rocker cover. A wire inside a wire?

Spyda I reckon your car is running super rich. That will explain why it runs badly at full throttle. You can put in more fuel, but if so, you need to make it brethe better.

So what do i do to fix this? I put a chip on but i also have the breathing mods, i know i dont have cam etc but other have the same mods and seem to be running fine eg. static.

I also agree with you, i think it is over fueling, it seems to go through fuel a bit quick, it always has but i thought that was normal.

Im geting a newish o2 sensor and the duel downpipe and mani tomorow, ill see how i go.
Should that help reduce it running too rich? Does the o2 sensor have alot to do with it?

Just to add, im not sure if this is a problem or not, but my water temp never goes past the fat white line. I dont have anything in the cooling system, just plane water (the color of coffee though). If i turn the rad fan off it will go up past the fat white line. On freeways it will drop to the end. Again, temp sender is new.

good luck with the mk2 saga. aren't they all a saga ehy?

solution to running rich = forced induction

have fun

Your car has no mods to help brething.
It has a restrictive exhaust and a chip that is throwing in too much fuel. The chip is probably designed for a european spec Golf 2 so with an aussie one it is throwing in massively too much fuel.

Sounds like the o2 sensor is dodgy and that controls lots of things with the ecu.

You need a thermostat in the car and some coolant. i`d change the temp sensors as they are probably rooted from sitting in coffee!

You need to put stock bits on the car until you get it running right then you can improve things. Using random BMW parts will not help it run right.

Good Luck

You mate me sound stupid, and your probly right haha.

I did put stock bits back on with no difference, as far as i remember it was like that with the stock bits.

The temp sensor is brand new, do you realy think it would be stuffed after 6months? The water is dirty, coffee colored, but i was always told that it doesnt realy matter. Is that true?

Did you put new stock parts? or the broken ones that came off it??

Coolant cools the motor. scummy water doesnt cool as effectively and carries bits of crud around to jam things like thermostats. And it will assist in corroding bits like heads.

Sweet.

About 30min ago, something els was added to the GOLFII to do list. The accel. cable snaped as i was backing out of my drive way and i live on a steep hill so that was no fun.

To do list:
accel. cable
master cylinder
O2 sensor
Flush cooling system
thermostat
power steering pump
speedo cable

thats all i can think of right now, guaranteed something els will brake.

[peedman]

If u wanna flush the system just take the top and bottom radiator hose off and run a hose thru the top one, then give the motor a rev to circulate the water. Prob best to take ur thermo out at this point so that the gunk doesnt get caught there and u can put a new one in.

[evorobin]

Drained the coolant on the mk1 today THEN took the thermostat out and still got served coolant lol

Static Came to visit over the weekend. We had a hectic Saturday at the shop and took out his strangler exhaust manifold and replaced it with the euro spec ones from a Mk3.

Here they are side by side.



Static last seen heading south in a red Mk2 making a bit more noise than when he arrived

I reckon he`ll give us a review of the mod

[static1800]

More noise and more speed the replacement cat was a good choice too

Well worth the effort of putting in, can't believe they released them with that downpipe and manifold, never realised it was so small and restrictive!!!

All you aussie mk2 guys hit loon up for a downpipe and manifold asap!!

[Spyda]

Where do you put the O2 sensor on the duel down pipe?

[peedman]

The o2 is after the down pipe right before the cat on a mk3. Those exhaust manifold bolts are pesky, it sucks esp when u round em off!

[Golf Loon]

Where do you put the O2 sensor on the duel down pipe?

In the Cat. We used a Seat one which fits the Mk2 nicely and the Mk3 downpipe and has provision for the o2 sensor. You could weld a nut anywhere on the downpipe for the lambda.
