Disconnect ignition coil No. 1 electrical connector.
Measure resistance across primary terminals.
Should be 0.40 - 0.50 ohms
You can test that but I don't really think it's a coil. It sounds like a fuel issue. Check the pressure and look for any leaks. They may be really small. And it wouldn't hurt to try a fuel system cleaning.

Yeah if your coils are bad it would run really rough all the time.
I don't think it's the TPS because you only have this problem when your in gear and the engine is under load right? If you can bring the rpms up when your in neutral just fine then the tps sensor sounds like it's working. Now if this problem occurs both in gear and in neutral than yes I might be a tps sensor. If you have some sort of scan tool that shows data it is really easy to check the sensor.
And if you want to be sure that it is not spark related just go pick up a cheap spark tester from a auto parts store and just check it at every wire before the plug. I think there like $5 and there very easy to use.

nope it is still hestitating jerking when past the 2500 k rpm mark in gear,but one time i was low in coolant to the point the car was starting to heat up at night , but at that time the car accelerate rather smoothly1!??
They say it can be my crank sensors?
I have not checked the timing since the timing belt may need to be replaced anyway.
I did replace the tps with another one still the same thing!

timing off two teeth the mechanic says
I have had the car diagnosed and they say the timing belt is off two teeth!! I am going to replace the t belt today by my mechanic. CAN that be the cause of it having no power past 2500 rpm approx and sputtering past that. thank you
