In your case, possibly a failing TPS. Also probably needs a throttle body overhaul. Run some Seafoam in the gas to see if the injectors will clear up. Seafoam actually dissolves hard deposits, not just the soft stuff. Injectors may be tired. I had to replace my '90's a couple years ago. Also, with a badly stretched timing chain and a cam only slightly less pathetic than the 318 of that vintage (like mine), you're losing vital response and performance. Time to get dirty.
