Anyone know what the problem could be ?
Here's what happens: I'm rolling along, and everything is normal.
All of a sudden, I feel a change in my motor's response.
Now, the motor constantly shakes, and it chokes much easier.
I have to give much more gas for the car to start moving at a stop.

Then, I'll be like this for a few minutes, and all of a sudden, wham!, everything's back to normal. The motor snaps back to normal. It does this intermittently.
Last weekend, it didn't happen at all, in fact my cel turned off by itself yesterday, only to come back on a little later, after another incident like the one described above.

Cel codes 72, 73, and 74 indicate that cylinder 2, 3, and 4 are misfiring or a having random misfires...

A friend of mine said this could be due to oxidation in some wiring...
Any of you have additional suggestions?
Thanks

I had 2 of my cylinders misfiring on me a few weeks ago. When I took out my injection coils to checkout my spark plugs, I had oil leaking inside there. I changed my cover gasket and spark plugs seals along with new spark plugs and lemme tell ya, I feel my lost power that I have been losin for some time. But it doesn't hurt to check out that area.

Okay, I'll check it out... Also, I forgot to mention that the engine (when experiencing the problem) will almost choke when idling.
It's getting annoying !

Oh, I had my car start to jerk and stutter when I was at halt. The RPM was all whacked. Mine turned out to be the EGR valve. Not sure what car u got but mine has one. I got headaches after headaches. As soon as u fix a problem, another one happens. Its like Tiger Woods. One hoe is discovered and as soon as he fixes that situation, another tramp pops out... Dammit lol
