Sluggish Problems????

Hibbz · 29-09-2006, 07:09 PM

Ok guys my car is a: Au3 auto Forte i6

Now my problem started that when it got below quater of a tank it would have a lot of lagg between shifts if you put the foot down a bit, even more so if you had just exited a turn. So i just didnt let it get below quater tank and it was fine.

Then the same problem started occuring from half tank down. So i called me mechanic whos a mate of my old mans and booked it in.

Then a couple days before i was taking it to him it started gettin really bad where it would stall and the revs would drop till ya took ya foot off the accelarator then sometimes it would come back up to idle and others it would just stall.

The mechanic said it could be a lot of things and said he would decode the computer and see if theres any faults and found that there was errors with the leads and coilpack.

So he replaced:

Coilpack
Leads
Plugs

Cost:580 including labour and decoding

Jumped in the car and it is still doing it so went back to see him and he said that those issued had to be fixed before we could move further but i have run out of cash for now so i couldnt go on with the change random parts till its fixed attitude.

Can anyone shead any light on my problem.

Leads, plugs and coilpack all replaced, that leaves (in order) ISC valve on the TB, O2 sensor or MAP sensor. Could also possibly be the power steering sensor, but doubtful.

May sound basic but try changing the fuel filter and fuel pump sock.

yep.... good call definately sounds like a pressure problem... maybe even replace the complete fuel pump assembly...

Quite poor form to replace the spark related items when you described quite well that it was fine over 1/4 of a tank of juice

Srry forgot to mention fuel filter replaced

He said the next port of call is the fuel pump but i dont really have and endless supply of cash being an 18 year old fella at uni to just taking these stabs in the dark.

Whats a fuel pump worth and a fuel pump sock??? and can it be fitted fairly easy by my self???

Thxs people replys are great.

Another question should those sensors be replaced or can they be cleaned???

As above

They can be cleaned to a point but really if they aren't performing you should replace them. The good news is they can both be tested to see if they need replacing. Ask your mechanic to fault them before he goes ahead and replaces them.
