Hey there, Sierra!
Alright, sounds like you tackled the spark side of things with the new plugs and coils, that's good! But a P0201 code for cylinder number one misfire on your 2.7L Sebring can have a few other culprits. Let's see what might be going on:
1.) Fuel Injector Blues: Fresh plugs and coils mean better spark, but if the injector for cylinder one is clogged or faulty, it won't deliver enough fuel for proper combustion. This can cause a misfire. You could try a fuel injector cleaner additive, but sometimes these guys just need replacing.
2.) Vacuum Leak: Vacuum leaks can mess with the air-fuel mixture going into the engine. If there's a leak near cylinder one, it'll run lean and misfire. Take a can of compressed air (used for dusting electronics) and spray around the intake manifold, especially near the first cylinder. If the engine idle changes when you spray a spot, that's your leak! Fix the leak with a new gasket or tighten any loose clamps.
3.) Sensor Issues: A faulty sensor like the crankshaft position sensor (CKP) or the camshaft position sensor (CMP) can confuse the engine computer and cause misfires. These sensors are crucial for timing the spark and fuel injection. Checking these sensors with a multimeter would be a good next step.
If you're not comfortable with troubleshooting further, a mechanic can run diagnostics to pinpoint the exact problem. But this should give you a good starting point.
Once you've identified which part needs to be replaced, click this link to be directed to our website where your vehicle information has already been entered. Simply enter the part's name into the search field to get started.
Good luck to get that Sebring purring smooth again!
