Runs good and then sputters

[oldnavy]

I have a 89 festiva lx and I have replaced the throttle positioning sensor, mass air sensor, new fuel filter, spark plugs( & wires), . fuel regulation is 40 so its good. Now heres the problem: runs good on the flat stretch, but when you go to pull out it wants to sputter, sputter and then rpms kick in. Could it be the sending unit, electrical, fuel injectors need replaced??????? I 'm lost at this point and any help would be appreciated. I did order a brand new throttle sensor instead of dealing with this used one.

running problem

i have the same problem with mine every once in a while, then again im using a mazda 323 fuel pump ! it could be vacume leak or the air cleaner is dirty ?

Would doubt the fuel injectors..they're typical create havoc at all driving condition.

Would also doubt a vacuum leak....they typicall provide rough idle and better performancewhile accelerating.

Sounds timing/ignition related....bad rotor and/or cap....loose/skipped timing belt....bad base timing....bad distributor or pulse pick up

Thanks for the reply! My next door neighbor is a semi retired mechanic and he replaced the accell coil i had purchased and put in a chrysler coil of he same voltage? It seems to work, but I should get the original coil for it and eliminate that problem. I will try rotating the distubutor next. Thanks, Lee
