View Full Version : XE holding back?
Guys just got my XE on the road it will tick over ok but it sounds really 'tinny' and holds back under acceleration really badly has anybody any ideas.
I was thinking something like the coolant temp sensor or an air leak.
Also i dont currently have a lambda sensor fitted but dont think that would cause the problem but i could be wrong.
Any help appreciated rep waiting for decent suggestions.

that would make the car just chuck the fuel in, as it cant measure the emissions

But that wouldnt cause the holding back would it?
Get a new lambda in, might want no plugs too if they've been washed clean in fuel.
afm?
Changed the afm mate got one off a lad on here shouldnt be that?
There is a bit of a flatspot though but thinking thats because the lambdas not plugged in.

Just fitted brand new plugs benn when engine went in.
Plug it in, check your plugs. Bet it will get better quicky (might need a few good starts/ecu resetting to see the change)
*but if its been chucking extra fuel in it might have washed them and they might not fire nicely.

pinking? timing ok?

I'm having a similar issue with my project corsa and its an air leak, it idles fine but seems hesitant to rev. people told me it was the timing but i double checked it and it was fine and the problem was an air pipe not connected on the throttle body.

Timings spot on mate doubly checked it it think the tinny sound is just the tappets to be fair as it hasnt run for ages.

Can it be any of the above or is there a specific one out of the 7 that he needs?! lol

Ill have a check round throttle body mate im thinking the same too.
Just to add when i put the mpi pump into the tank it was a tight fit to bolt down felt like it had sat on the bottom of the tank as i was bolting it down are they nomally like this and would this cause this problem?

that would make the car just chuck the fuel in, as it cant measure the emissions It will have funk all do with the lambda, its ignored unless the engine is idling or on light throttle.
The ecu runs the engine entirely off the map when its under load. :thumb:
Has it always ran like that or just randomly started? Could well be the fuel pump!!!
get a lambda sensor on it. Will NOT run right without it, and will hold back bog down overfuel.
You are wasting money throwing things at it without doing the lambda first

Mine throw its toys out cause i was driving it with no lambda. Wasn't bad on idle but when drive it was bogging down and ran like crap.

Ihave no idea ad i got the engine off a mate so i didnt know anything about it todays the first time ive driven it think its been stood for bout 5 months.
The fuel pump was one from the scrappers off a 1.6 16v astra.
I drove mine with no lambda and it drove fine, just the ecu light came on when it was idling :confused:

Absolutly true mate im in the middle of sorting one for it as we speak.
But as adam says though once under the load the engineruns off the ecu map dosnt it?

Sound like the same sort of problem benn did it run perfect as soon as you connected the lambda?

Has everything to do with the lambda. It will be using a base setting and guessing at what it needs to run. Putting your footdown will just make it bog down and hold back. It may cancel out under throttle but if its wrong in the first place its not going to fix itself
Worth a try i spose.
Mine ran absolutely fine without the lambda though.
Is it a dispak engine or dizzy???

Ive had plenty of redtops, ive had problems with the o2 sensor on every single one exept my last nova which had a 20xe so no o2 sensor to go wrong. Still had to set the fuelling up via the afm

It will always use the map base numbers under load. If the ecu was using the lambda sensor readings and looking for a 14.7afr with your engine under full load, it would be running lean as fcuk :thumb:
your just a lucky ****** then lol
I drove mine with no lambda and it drove fine, just the ecu light came on when it was idling :confused:
Same as my mate did ad he ran his dispack XE with no lambda an it ran fine?
It may be the dissy ones that need them to be plugged in?
Whats yours dissy or dispack?

Mines a dissy type ad.

it may be looking for 14.7 while running at idle then adding in a modifier for varying throttle positions to account for running rich on acceleration (it wouldn't actually run lean technically, but it would run stoich which is lean*er* than it should be) Could well be the lambda throwing it out

have to remember Adams engine is amazing, 180bhp for a start lol
Mine is a dispak engine Damen
Sound like the same sort of problem benn did it run perfect as soon as you connected the lambda?
YES>
Mine is a dispak engine Damen
That may be why itll run without then ad same as my mates. With mine b eing a dissy type it may need one to run right as benn said about his on the first page.
Just fit one, take the ecu out so it resets and try it.
YES>
Right then so ill get a lambda plugged in before i start messing with anything else and see what happens like you said mine seem to be doing exacly that mate.
Have some rep thanks for the help again benn.
lol
must spread the love benn

Good good, "reset" the ecu/a few good starts and i'm sure you'll notice its sorted.
lol

i tried aswell :(
Just to add to this thread just incase anyone else has similar problems today i fitted the lambda sensor and it has cured my problem it pulls like a train now and dosent bog down under full throttle.
Cheers for the help guys.

har ****ing rar lol
i want rep bitch lol

^^^^lol yes you were right...........
yea rep on way haha.
Cheers nick.:thumb:
im sure my lamda sensor was never plugged in, my knock sensor went and caused alot of running problems

I found out that it depends on if its a dispack engine or dissy bubba if its a diisy engine they need them plugged i to run right but the dispack ones dont as my mates is a dispack one and hes never had one plugged in and that runs fine.
mine was a dissy...oh wait yes it was plugged in, coz i ripped the plug out taking my exhaust off

right another question,
you did not have an o2 sensor, was there just a hole in the manifold? was it a bit blowy? did you not think, ooo i need to stick something in there ?
Hmm, must be a dizzy engine "thing"
General Baxter
24-02-10, 09:35 PM
your old x16xe ran fine with out one aswell lol
Yup.
You couldnt even tell the lambda wasnt plugged in on my xe.
Maybe its because the dispak management is better though.
General Baxter

c16xe needed one lol
Well look at that... lol
Yes yes you all said i needed one lol.
Give me a dunces hat an i will sit in the corner so you can laugh. :d lol

Ah well i had already put a blanking plug in the hole nick so it wouldnt blow lol .
Hmm, must be a dizzy engine "thing"
Must be ad like we said dispack engines run fine without.:confused:
Yup.

Yea must be down to the better management setup on the later engines.:confused:
my dispack engine ran crap with out one lol
my dispack engine ran crap with out one lol
Theres always got to be one ^^^^^lol lol
Hmm, must be a dizzy engine AND RICH's DISPAK ENGINE "thing"
Better? :p lol
Better? :p lol
Haha ^^^^lol nice one ad.
