Several years ago, I bought an inexpensive' Code Reader.
This is the device you plug-in under your steering wheel when your Check Engine Light comes on.
Wasn't used too much except to confirm I had NO 'pending' Codes.
Over the Summer it was needed twice.
Both times the Check Engine Light came on. But their also good at checking for Pending Codes.
Do your repair and Delete any Codes. Recheck several days later.
1.) Driving down the road and engine feels like it's hesitating every 10 seconds.
Ended up changing the Throttle Position Sensor. $30.00 part at Auto Zone.
2.) Driving down the road and at every red light, I get a Rough Idle.
Ended up changing the Spark Plugs. $45.00 at Auto Zone. Bought Iridium this time.
These Code Readers are a great diagnostic tool for the DIYer.
For the small amount of money (maybe $50.00), way better to own than relying on an Auto Store to check for you.
A side note: I have to watch the 'gaps' of Spark Plugs.
I removed Motorcraft (platinum) after 37,000 miles.
3 plugs on drivers side had a .080" gap (should be .044")
Passenger side plugs had .046" gap.
Other than the gaps being over, every thing else looked good.
