Mitsubishi Carisma Engine Trouble

If your car has an ignition module you might want to check that next.

Sounds like Water temp sensor troubles , If its faulty it will tell the engine its -65,C In other words pretty cold . When the engine warms up, it still tells it its icy cold ,In other words full choke. jonny .

The 96 Carisma appears have either a 4g15 or 4g93. Since the problem occurs when the engine is hot, the first thing I suspect is the tappets are tight. As an engine ages, the valves tend to wear into their seats a few thou, and cause the tappet clearances to be reduced. This means the valves don't fully close, and rough running results. When the engine cools down a bit, the valves seal properly and the engine runs.

The 4g15 is known to be susceptable to tight tappets, 4g93 likely also. Get them adjusted and see what happens.

No it's not. The original poster says "From cold, the engine starts first time.". If the water temp sensor is faulty or disconnected, starting from cold is often very difficult.

I beg to differ BUT, ...... When the motor is cold the tappets are tight ,And the engine has starting problems.When the motor is warm the tappets open up and the engine runs ok . This is a common starting problem with colt/lancer that have not had regular servicing, Never experienced this on carisma . Absolutly worth checking the tappets though , jonny.

Hi ,

What engine is in the vehicle ?

This vehicle has either a 4G92 1.6 , 4G93 1.8 or F8QT 1.9 with adjustable valve clearances or the 4G93 GDI with hydraulic lash adjusters. And tight tappetts wont cause the check engine light to come on. The 4G15 was never fit into the Carisma.
