Dear Mr Anthony Falcone,

I hope you can help since no one in Australia seems to know what is wrong with my car.
It is a 98' Mitsubishi Lancer CE coupe 1.8litre.
I recently had a CA-18 turbo put in with custom manifold and twin exhaust. A unichip piggy back is used to regulate fuel and a high flow fuel pump and high flow injectors. Since I had the turbo put on, even before I put on the piggyback computer, I had these following problems:
1. rough idle
2. idle drops below 800rpm sometimes, and sometimes it stalls but at other times its OK
3. engine switches off sometimes during a slow right hand turn
4. there is a blue silicon hose joing the back of the airflow meter to the metal pipe leading to the turbo which is very soft and when I squeeze this, it tends to stall the engine. Could the engine vibrations be distorting this hose and therefore affecting airflow meter reading and so stalling the engine?

I have had technicians reset the idle motor already, and this seemed to help with the idle a little but then just now it switched off on me during a slow right-hand turn. I am so frustrated! PLEASE HELP ME

I'm not to familiar with the turbo Lancer sold in Autralia. But this problem does sound like a fuel issue. Depending on your mods and emissions regulations in Australia, you may have an EVAP problem. This is the emission control system that prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

If any of the emissions components are failing, that will contribute to rough idle, low idle, and stalls while turning. That tube you squeeze that tends to stalls the engine may be an emissions hose. The engine virbrations should not be causing your problems.

With all that extra fuel you have going into your engine from the fuel system upgrades, it may be putting extra stress on the emissions system Have your emission system checked. You may just have a stuck vent control valve or purge solenoid.
Good luck!
