Yesturday my truck started acting like it was having a hard time running/accelerating. We took it to Shucks, and they said it was the spark plugs that needed changed. We changed all 6 of them today, the really bad one had some kind of oil on it. We bought really good spark plugs, and still my check engine light is on. And the car stinks really bad like burned rubber. Also if I get to 30mph the check engine light starts to blink.
Im so stressed about this, does anyone know what could be wrong? Has anyone had a similar problem????

Re: check engine light
Did you overheat the vehicle?..if oil is on one plug severely you may have mechanical issue (rings/valve stems) leaking into cylinder...get diagnostic compression test and leak down and scope electrical secondary system and advise me results

I have the same problem. But my check engine light comes on when this occurs. The car runs fine otherwise. The problem manifests when it's hot out and I've been driving for a while with the A/C on. When I stop somewhere (like the supermarket), shop, and get back in my car. It starts fine but when I put it in gear to go, it's extremely sluggish for a few seconds and the check engine light comes on. Then is runs fine but the check engine light remains on. The next day when I start it, the check engine light is not on. Also, I recently had the head gasket replaced. I took it back into the shop the first time the check engine light came on. The mechanic checked it and said everything checks fine. He re-set the light saying to keep an eye on it and bring it back in if the check engine light comes back on. It ran fine for 1.5 weeks and now this problem has started to occur.
Did you find anything out dwbradway? I wish I had a solution for you but I just have the same kind of problem. Any help would be appreciated!
Go to your local shucks or auto zone and they can check any codes behind your check engine light and it's free. It sounds like one of two things a O2 sensor or your mass airflow sensor but they will tell you for sure
sounds like you have a fuel delivery problem . if the engine is slugish and set code for random missfire more likely is starving for fuel.check fuel filter and replace it. check fuel pressure you may need a fuel pump. i hope it helped you.rate me and if you need more help let me know.
First of all, you should'nt do this unless you know what the problem is.. or what tripped it. I had this problem when my husband and I were replacing a head unit and disconnected the old head unit, a/c and other stuff then turn the car on. This made the light flash. The first time we took it in and got charged $50 to reset it. The second time we did this procedure and it worked.
ECU Resetting Procedures
Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON. A stop watch or an analog clock with a second’s needle will be useful.
Reset Check Engine Light Procedures
1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds. 2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds. 2a. Fully depress the accelerator pedal (HARD). 2b. Fully release the accelerator pedal. 3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking. 4. Fully release the accelerator pedal (while the CEL is still blinking) 5. Wait about 10 seconds. 6. Fully depress the accelerator pedal and keep it for more than 10 seconds. 7. Fully release the accelerator pedal (The CEL light will continue to blink). 8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.
