My check engine light came on and went off three seperate times during my morning commute. I know I need an oil change desperately. Could that be the problem? Also I saw a small amount of reddish fluid under my car this morning? Could that be the problem, and if so how do I fix that one?

Re: Check Engine Light
Reddish fluid can be
oil (dipstick on motor)
transmission fuild (dipstick on transmission)
brake fluid (transparent reservoir on vaccuum booster)
power steering fluid (transparent reservoir on PS pump)
maker's dye choice for the fluid filled,
Check fluid levels and top up any that are below recommended levels immediately, then monitor fluid levels and fix any that show evidence of leaks.
The check engine light is an indicator, it just says that 'something' in the list of functions it is monitoring is not right. a code reader can be plugged into a socket under the dash to reveal the most recent error codes.
Many repair shops (around here) will read the codes for you gratis, in the hope of getting the repair job.

Service engine soon or check engine light? Engine light needs scanned for codes. Service engine soon is for oil changes and such. To get rid of service lights, turn the key on, press the gas pedal three times within five seconds. The light will flash. turn the key off. it's reset. At least check or change the oil and filter though.
What you do when the engine light comes on is to stop the vehicle ---check the oil level and let it cool down then check the coolant level at the radiator. The engine light is the message to you that the CPU has found sensors /servos that have gone outside set parameters and your course of action then is to prove that the engine is safe then run the fault codes to find the recorded faults and fix them . use the code reader to reset the CPU to ensure that the faults are fixed.
Hi, the Check Engine light and the cruise light blinking tells you the computer found a problem with your vehicle's running condition but if the vehicle is driving OK, a Check Engine light is not a reason to pull over and get the problem fixed soon.
In testing areas, you will fail your emissions test if the Check Engine light is on and fuel economy generally suffers when the Check Engine light is on.
When the Check Engine light is on, one or more "trouble code(s)" are stored in the computer and you can read and erase trouble codes using inexpensive code-reader tools from auto-parts stores; the tools are very easy to use.
The problems identified by the codes are frequently easy to fix (such as a loose gas cap), but some are complex, requiring professional diagnosis.
A trouble code indicates a circuit where the problem was identified, not necessarily the component itself. Diagnosis is often necessary.
try changing your pcv valve. if its dirty it may be causing the shuttering. as for the check engine light going on and off, you may have a bad gas cap. if the cap is faulty it will cause the engine light to come on at times because of a poor air to fuel ratio.
Change out your oil cause its low or dirty. Take the thing into the auto parts store or a mechanic so they can hook the thing up to their computer and see what trouble codes come up from the check engine light.
Try running some fuel injector cleaner through the fuel system and going up on the fuel octane rating. The fuel octane rating for the car is 87, try running the 89 octane for now. As the car get's older, carbon builds in the the cylinder and valves and they may be causing the detonation during the morning drive up the hill. As the engine advances the timing for more power going up the hill, it sounds like it's causing the misfire. A higher octane rating fuel should help this and a clean air filter too. The check engine light is just indicating that there is an issue with the engine and it's compensating the problem. When the light comes on when there is a misfire, the engine's ecm will turn the timing back and will bring the timing back to where it should be at the next start up. If you do mostly city driving at short duration, there will be more carbon build in your engine and changing the oil and filter is a must more then doing long hi-way drives. Good luck and keep me posted, be glad to answer any more questions you may have.
you might try and change the pcv valve, my car hand a similar problem in the summer and i never changed it. the pressure blew my cam seal and i was leaking oil like crazy. i dont know if it will fix it but they are cheap. i would give it a try.
I would have the front brakes checked and from what you are telling me you may have a warped rotor I do not know how many miles are on the car some cars have a reset after the oil change has been done to turn off the check engine light but if it keeps coming on take it to autozone and they will put it on a tester for free and then you will know what needs to be done
