I have an issue with my car and I am wondering if anyone here can point me in the right direction.
Car needed a lil' tuneup, so I changed the following today :
Spark plug wires
Once I was done, I started up the engine. It ran fine for the first minute and then it started to bog and moan, almost stalling.
I quickly made a video to show what happens. (Can't really hear the engine...didn't think of opening the windows, but you can judge by the RPM and battery meter).
When the engine is cold, RPM will go up and down to start (which I think is normal, but I can't say that I noticed it before), and then it steadies for about 30 seconds to 1 minute (but even then the rpm wobbles between 700-900). And then it starts to idle really rough, car is shaking at that point, almost stalling, but it revs back up just in time to avoid the stall.
If I rev up the engine passed 2000 RPM it seems to run just fine, or maybe it's just hiding the problem at that point? I'm really at a lost as to what could be going on.
I triple verified the spark plug wires and firing order on the cap and they are fine.
Here's the parts I put in the car :
52913 - Ford Motorcraft OEM Spark Plugs (87-95 5.0L)
14212 - MSD Super Conductor 8.5mm Spark Plug Wires - Red (79-93 5.0L)
14230 - MSD Replacement Cap & Rotor (86-95 5.0L)
14205 - MSD TFI Performance Coil (86-95 5.0L)
Any help is appreciated. Thank you!!
