Engine Malfunction / Reduced Power
Good time of the day. I have received a dreadful message from my car today "Engine Malfunction/Reduced Power".
Happened when I was doing about 70mph on the freeway, immediately lost the power and redline went down to 5kRPMs. Made it home safely but on the away at every stoplight it sounded as if it was choking on itself and lots of shaking. As soon as I approached my drive way the car just died on me. I tried starting it 3 times and it failed. Decided to put the key in (it has comfort access) to unlock the steering and push it the rest of the way, but then gave it another try. It started, the Fault Message went away, but the symptoms of the limp mode stayed the same. Started it 2.5 hours later and same story, shaking when idling and sounds like its about to choke on itself. Like its missing a few cylinders or something.
a few things to consider:
It has happened to me before after doing 140mph in MDM but the symptoms were nothing like it(no shake, no weird sounds), I ignored it because I needed a new
Voltage Regulator at that time, which would give any sort of fault code due to malfunction at the time. Replaced my Alternator in whole, had no issues whatsoever since then.
Another thing, I have been driving around with Increased Emissions for quite some time, due to a bad Thermostat, got the new one but never had the chance to replace it still.
Also for the past 3 months every cold start sounded like the engine was "flooded", RPMs would just jump from 700 to 1200 for a few minutes until warmed up.
The car is 90,000 miles old.
I have no idea of the previous records regarding spark plugs or anything like that. Already thinking about Coil Pack, Brake booster, Spark Plugs themselves, Pressure Differential Sensor. I just hope its something replaceable and I dont need to say bye-bye to my engine because of worn down Rod Bearings.
will have the codes read soon. while I'm at it, any of you kind gentleman have an idea of what can possibly be wrong?
Thank you for the time.
