My sr breaks up-light throttle(HELP)

[ownedbypandas]

Alright Im having a issue with my sr. And this only happens at very light and low throttle 5-15% range. It is basically impossible to drive the car at a cruise around the street, i have to either be on it or off. If Im driving and i give it light throttle it chokes, its like the car doesnt have any fuel, it sputters and breaks up bad. Once I give it more gas it goes away and its fine. Now at idle and sitting still if I give it very light throttle the car with start surging revs up and down up and down up and down. I dont know where to start. I have a safc2 hooked up to it(i double checked all of my wiring and everything is good.) and im getting a signal from the maf and the tps. Have any of you guys had a problem like this or can give me some pointers to touch. Thanx a lot guys

Start basic and at a starting point. Strongly encourage you to check for vacuum leaks. Many ways to go about this check, I'll leave it up to you to figure that out unless you don't have a clue- then let me know. 2nd check your tps for correct clock. Voltage reference and if its still available (its been awhile since I checked if the download for the SR manual) the technical manual for an SR's specified references. Then start going through your timing on your Crank position sensor and make sure thats timed correctly. I think if my DIYs still work I'll have the timing DIY.
