Hey guys have a problem with my 94 m6 lt1. Just replaced the distributor and coolant temp sensor on the water pump. Car was sputtering and bucking under hesitation before now when it idles, it idles super rough jumps around on the rpm but doesn't stall until you start driving. Took it for a spin a day ago and under the load car runs fine but when you start off gotta give it a ton of has for it not too stall and the idle is bad. Don't know what it could be replacing the water pump tomorrow and got a new coolant temp sensor, don't think that will resolve the issue but been wanting to replace the pump so doing that, any ideas? Thanks

What kind of distributor did you use?

Make sure that your elbow is on correctly. Make sure all the lines after the MAF are installed correctly.

Ya man everything's on correctly I took that think off bout 5 times after and everything's on right

assuming you installed it correctly and plug wires are on right and all sensors hooked up....the above opti is a very likely candidate for problem

use a AC Delco or Delphi opti

Any backfiring?

Ya checked wires bout 5 times all Hooked up in correct orders, don't think it is cause I drove it around the block and when you get on it no hesitation at all. Just on idle very difficult to start moving cause Rpms bounce

No backfiring, doesn't seem like it's misfiring best way to explain it is that it sounds like when a car is leaking air the rpms constantly go up and down, but I don't think it is I did a smoke test and nothing as well.
