A rough idle and lack of power in a 1994 Mercury Tracer when hot could be caused by several issues. Common culprits include a failing ignition system (such as spark plugs or ignition coils), a clogged fuel filter, or a malfunctioning fuel pump. Additionally, a dirty or faulty mass air flow sensor (MAF) or a vacuum leak could disrupt the air-fuel mixture, leading to poor engine performance. It's advisable to run diagnostic tests to pinpoint the exact issue.

Why does 1993 mercury tracer stall at red lights when warm?
Most likely a bad idle control (also called IAC or ISC). Otherwise, it it also seems to run rough, consider the possibility that it might be overdue for a tune-up.
What causes fast idle on 1998 Mercury Tracer?
Fast idle on a 1998 Mercury Tracer can be caused by several factors, including a malfunctioning idle air control (IAC) valve, which regulates the engine's idle speed. A vacuum leak in the intake system can also lead to higher idle speeds by allowing extra air to enter the engine. Additionally, issues with the throttle position sensor or a dirty throttle body may contribute to erratic idle behavior. Proper diagnostic testing is essential to pinpoint the exact cause.

Why does the engine idle go up and sometimes turns off engine and down at stops on 97 Mercury Tracer?
The engine idle on a 1997 Mercury Tracer may fluctuate or turn off at stops due to several factors, including a malfunctioning idle air control valve (IAC), vacuum leaks, or issues with the throttle body. The IAC controls the amount of air entering the engine at idle, and if it fails, it can lead to unstable idle speeds. Additionally, vacuum leaks can disrupt the air-fuel mixture, causing the engine to stall. Regular maintenance and diagnostics can help identify and resolve these issues.
Idle rough when brakes are applied?
The power brake vacuum booster is probably failing.
