Engine running problem please help!!!
Hi all i have a 95 turbo 2000 impreza and in the last few weeks there has been a problem with the car it splutters and back fire's on pull away and on the power it couths and splutters to.
Now i have changed lambda,3 coil parks because all 3 of them was broken,i changed maf sensor to and i am still getting this problem i am going out of my mind trying to fix it but just cant find the sourse of it :-(.
Mods on car are
Front mount intercooler
Gizzmo boost controller
Full decat systerm
Up rated fuel rails and fuel pump
Turbo timer
Vf turbo not sure what number it was sorrr
Fuel reg
K&n air filter
Think thats about it on the mods.
So if any one could help with my problem please let me know thanks.
Regards alex.

To start with your air/fuel ratio will be all over the gaff
If i were you get it mapped asap and drive off boost or dont drive it till you get it mapped. Last thing you want is the engine to go.
.....or return it to standard, reset your ecu and put the mods back on before you get it mapped.

The best way to get the fuel and everything else set up is for the car to be mapped. The Ecu controls fuel, boost ect ect
You say you have a turbo 2000, but z4 ecu's are off import cars. Do you have a 2000 or WRX?

Ok i will try to book one up for next week.
When i was upgrading all the mods on the car i was told to put a z4 ecu on it so it would handle the power beta but yh its a turbo 2000.

I didnt think you could put import ecu's on uk cars. If so this could/has caused another problem.
Z4 ecu's are not mappable so you will need an ESL daughter board or an after market ecu (Simtek)
Contact Simon (jolly Green Monster) one of the best mappers around. Info and prices on his website

I would also put in a new set of plugs. That might be the cause of your sudden problem, particularly if you've had problems with coil packs. If your plugs wern't firing properly then it wont take long for them to fail. Id suggest NGK7's

Make sure you get it mapped as soon as possible as like has been said you are running the risk of blowing it up!

Thays good to hear. Your plugs failing is a sure sign that your mixture isnt right! If you dont get it mapped properly the least that will happen is you'll destroy your new plugs, at worst you'll melt your engine!
