Help my hatchie

The other day i started my car and the check engine light came on. it was way screwed up cuz it was idling at 2,000 and whenever i got over 3,500 it wouldnt push any farther. I drove it down the road, shut it off, then started it back up and it was fine. It did it once more since then so i restarted it and it was fine again. Whats going on with it??? Please help me. The engine has 200,000 miles on it but i cant afford a swap just yet. Is this the beginning of the end of my engine?

did u check the ecu to see what code its flashing?

no not yet. Do i have to check that while the check engine light is on? cuz it only does it every once in a while

pull the carpet back and look how many times the LED blinks

what carpet? i mean, wheres the LED

pull back the passenger carpet, where you feet rest. under the carpet there is a metal cover, idk if you can see the ecu light from there, if you cannto the you gotta take off the 4 bolts that hold the metal cover on. once the cover is removed, youll be albe to see the ecu light

only once. does that mean that it doesnt detect anything wrong?

well, it blinks once when the key goes to the on position. is that it just turning on or is that an oxygen sensor code

Have you ever changed the timing belt? I has the same problem and ignored it since all I would have to do was turn the car off and then on again and it would run fine. Of course a month later 'snap' the timing belt broke.... No bent valves which I was lucky but you should change the belt every 100,000 kms...

just replaced it 900 miles ago

This sounds to me like a timing or distributor issue. Maybe your timing belt has slipped a tooth or something. Maybe your distro is fried.
