The engine light is flashing on. Also car 'died' all power down briefly at about 20kms


I had this happen to my car after my mechanic said do not worry about oil light flashing intermittantly it is probably a sensor.
Now my car blows oil out the exhaust and is missing a cylinder or two and is hard to start and also lost power at about 20 km/h). I have done a ring or burnt out the rings which means a replacement engine ($3000 AUD) or replacement car is required in my situation. (too repair engine $6000 AUD which a different mechanic has told me they just do not bother repairing as labour is intensive and a reconditioned motor is cheaper)
(1) Check if oil is being blown out the exhaust pipe of your car when engine is cold. When engine is hot smoke with oil smell comes out. (burnt out rings)
(2) Check is Water is coming out the exhaust pipe of your car when engine is cold. When engine is hot steam comes out (blown head gasket possible if steam) (Cost estimate minimum $1500 AUD - depends on if head is warped or cracked)
(3) Check cooling water levels if running low all the time see (2)
(4) check engine has oil in it could be point (1) causing oil loss
(5) check all fan belts are working as designed and not broken

All of my warning lights and cruise control lights keep flashing randomly


not all faults show up as the same fault. Life would be easy if that was the case . However when there are a lot of faults exhibited and there is a loss of engine power The first thing that I check is the battery ,terminals for tension and clean and the drive belt for condition and tension. Lastly if the battery is failing many of the complaints will show up. I would suggest a load test done on the battery . If you got if from a car yard with that amount of miles on it I would question the strength and age of the battery . These suggestions may not fix the faults but at least you will have eliminated the major cause cheaply.

Blue smoke No oil consumption + more questions


white smoke could be coolant burning and not oil possible head seal on the way out or a leak in the jacket into the cylendars, check coolant levels are ok, also check oil filler cap and see if any creamy or gray gunk is showing on it, this would also indicate the same. you can also check exhaust with a cloth to see if a lot of steam is also coming out with the smoke. I hope this was useful

I changed the EGR valve on my '02 PT Cruiser about a year ago when I got the code, not the check engine light is coming on again but the car is running fine! I have taken it back to my mechanic twice to...


Its either a faulty EGR valve or it has carbon build up inside.Take valve off and clean carbon out using a non-chrlonated brake cleaner and wire brush.

Check engine light,engine miss,loss of kompressor power


might have a vacuum leak. 2005 c class 230 kompressors have issues with the engine vent hoses under the intake manifold deteriorating and coming completely apart. This will cause mixture adaptations to max out and can cause missfires. Usually it sets a check engine light when it gets bad enough. There is a factory recall to replace these hoses, so check with mbz to see if your car has an open recall

1986 ram 50 canadian 4 cylinder, turns over strong, wont start


To start out with. You left out some very important information. Like: the miles on the engine, the miles on the spark plugs, electronic ignition or points, but, I will attempt to give you some pointers and areas to check.
First off, I don't believe the rusty gas tank with the hole in it has anything to do with your problem. Dieseling... I guess you have to understand the differences between a gas engine and a diesel. Basically is: a gas engine runs on spark and a diesel runs on glow plugs and compression, lots of compression. True dieseling usually is a result of having a carbon build up inside your cylinders, usually on the valves. The carbon glows when it gets hot and when the engine turns over opening the intake valves it lets in fuel.Even when you shut the engine off it still makes a few turns, causing the intake valves to open letting in fuel and if there is carbon present and it's hot you may get dieseling. You also may experience what appears to be dieseling from having your timing off. It could be from having a timing chain "jump" a link, (alot of miles on the engine) or it could be from the distributer being out of time. Both may cause loss of power and the "appearance" of dieseling. It sounds like to me that you may have a lot of miles on this vehicle and it may be loosing compression thus causing the loss of power climbing hills. Loss of compression could be caused from worn rings, bad head gasket. The block section of the engine. Or: cracked, worn, or brokrn valves, the heads of the engine. Which may explain the dieseling. Bad plugs and bad plug wires can also result in the loss of power you are experiencing while climbing hills, but you would more than likely experience the engine missing, which you did not say you were experiencing.
You may want to check with a local salvage yard for another engine if the rest of the vehicle is "worth" saving or plan on doing a compression test and more than likely...some "heavy" wrenching and rebuils you engine.
I hope this helps you. If it does please let me know and put in a post about it.
Thanks!

Misfire


One question, have you replaced the ECTS (Electronic Cooling Temperature Sensor)? These cause no end of different seemingly unrelated problems on Saturns. Peice is about ten bucks and is an easy install. Just search on youtube for a how-to video. Even if that's not the problem it is reccommended to replace this peice just the same as they ALL end up going bad at some point.

If that's not a fix, start pulling plugs. Check to see if they're correctly gapped and if they have any damage/corrosion. If you're running Platinum plugs, immediatly change to a copper plug as Platinums have no place in these motors. Most people have the best luck with NGK copper.

Check to make sure that your plug wires haven't been crossed. This sounds like a plug or wire issue most likely so it has to be in that family, if the plugs are good, wires good and not crossed, sensors are fine, then time to replace your coil packs. If you've replaced everything up to the coil packs then that is most likely the cause of your dillema.

Sudden loss of power while driving


One thing you should notice that could tell you if the the engine is misfiring is that the check engine light will flash. If it dose it is saying you have a misfire in either one or more cylinders. If the check engine light dose not flash then it could be more of a fuel pump related issue. but as I said 1st thing would be to check the code... then i could tell you whats going on. good luck
