I took the 2006 4.4L to pick up some things at the supermarket on this wet rainy morning. Went inside and came back out 15 minutes later and nothing when I turned the key. In fact the ignition switch didn’t want to turn at first.
I took the jumper pack out of the back and the voltmeter read 12.5 volts. I thought that odd since she seemed dead. Go to start the car and nothing at first (can’t turn key) and then she started, all within 5 seconds. She idles/runs fine while I packed up the jumper pack.
I put her into gear and she won’t go above 1500 RPM, it’s as if there’s some types of limiter because she isn’t straining or misfiring. Forward and reverse gears are the same.
I limped home (2 miles) at 5-10 MPH but couldn’t make it up my inclined driveway to the garage, so I parked her in the pull off area by the road.
I turned her off and now she’s dead again, no lights, nothing.
I suspect it’s an electrical problem, but what puzzles me is the fact that once she was running it would not rev above 1500 RPMs.
Has anyone seen these symptoms before?
The vehicles has 165,000 miles and was running great before this. The battery is one year old (I’ll test it anyway).
No check engine light when she was running. I’ll try to read for codes if I can get juice to flow again and turn the ignition switch on.
Very strange... and of course it’s raining and she’s 300 feet from my garage, and I’m going in for knee surgery in 18 hours.
