Someone please help i just put a 98 motor in my 95, its an auto and i took it out after a couple days of driving it ,and i decided to go Wot and when i slowed down almost to a stop the car started shaking and bucking.I only have the code 0201 ive replaced the coils and injectors and i still cant seem the figure out the problem .Ive even checked the cps sensors with a multimeter and they all are fine. The only thing i notice is, when i turn the key to the on position the tps will buzz and it doesnt stop until i start the car or turn the key to the off position.



PLease help and excuse my typing errors im fustrated

 

have you checked to see if the TPS is busted? that might be a really good place to start, since its buzzing you know. ohm it out first then if you have an extra try swapping.
actually, try seeing if your MAF is fried, it sounds an awful lot like that.
can you take it above 3k?

 

Try disconnecting the battery for 1 or 2 hr, so you can reset all the codes and disconnect the TPS after the battery has been disconnected. This way you will know what was really wrong when you pull the codes again. If you have an extra spare TPS part try using that and see If that will make a difference.

 

I will try these and i'll get back you with results
