i drive a 1993 sentra se-r with 120,000 miles on it,when i bough the car
it was fine, it was as fast a stock se-r should be and i had no issues with it.
about 3 months ago the car started hesitating and surging when cold, the problem would go away when it was warmed up. i ignored it becuse it wasnt really bad and i was broke, well recently it has gotten really bad. it surges and hesitates violently when cold, when it is warm it does this about 1/4 of the time.
it also is really slow now, almost like it is ga16 powered if i get into it and put my foot to the floor it will go, but after 4k-4.5k it feels there is a drop off in power. It feels like its at half throttle(even though my foot is to the floor)
i cleaned my throttle body, regrounded my maf(correctly), and put new pkugs and wires in, but still the same problems. anyone have any ideas what could be going wrong? this car was a blast to drive before the problems, and now i hate
driving it. i want to love my se-r again!!!!!!

i should just take the car into a field and set it on fire

Definately sounds like something is wrong ! Do a compression test perhaps? Pull the valve cover and check for sludge

for one... if its hesitating at cold start ups, you might wanna check your temp sensor. i had the same problem with my car, i had a faulty temp sensor and during cold start ups it would hesitate and stall. i had to keep it reved until it got warm. i got a new temp sensor from autozone for $25. and as for your power feeling sluggish, you should check for sludge build up in the motor.
