Having problems with your Cars & Trucks ?

What causes the 2002 ford focus to be lazy? - Cars & Trucks

Posted / edited by AnonymousUser on : 12-11-2018

Answers :

The main, common issue with the Focus was the intake manifold. It's made of plastic and is prone to cracking and it's inner butterfly flaps cracking off and entering the engine, causing issues and failure in extreme cases.
Also check the catalyst condition. I've had one focus with a meted down cat, which caused blockage in the exhaust system, dramatically reducing power.
