OK so the car losses power at any speed. When i floor the motor it will kick back in until the RPM go back under 3500(shifting of transmition). if i feather the gas it has power... but cant gain speed. if i floor it tranny kicks gear and it runs good again, only till transmition shifts back into normal runing gear(bringing RPMs back under that 3500 mark). doesnt always have this problem... if i turn the car off for a min or 2 it seems to run good for another 10 miles then has the problem again. Im wondering if the enigne has a fuel distubuter in it. i know moters with those can have same problem.... Engine also seems to be missing when this happens.
Check your fuel pressure, should be 40lbs+ at idle. If you dont know how to do this, have a friend or a shop check it for you. I had same problem, no power at all would barely run ect,, turned out to be fuel pump.
Could very well be the fuel injectors. have you tried putting fuel injector cleaner in when you filled the tank? always with a full tank of gas.
You need NEW spark plugs and spark plug covors.
