93z28 Fresh 383 stroker build cc306 cam all the supporting mods Holley 58mmtb TPS slotted everything's done right or so I think.. Regulars less of the car being in closed or open loop as soon as its semi warm it will either die or choke out when ou step on the gas. I have disconnected the o2 sensors no difference, the car has a Solomon tune and was running fine until recently. Fuel presure is fine, brand new plugs wires everything brand new build. Walbro255 fp 38# injectors... Tried a new TPS iac nothing. Messed with the idle screw nothing. Not sure where to go from here

Water temp sensor? (The one in the water pump).

Would that cause a rough idle or intermittent dying problem or wouldn't that keep th car from starting period? I know when I did my opti the car wouldn't start period when it was unplugged, never had one to bad though.

I've never had one go out on my car, but from what I understand those are the symptoms when they go bad. When the car is cold does it start giving you problems when it switches from open to closed loop? If the sensor is bad then when the car goes into closed loop the PCM will think the car is much colder than it really is. Does it smell super rich?

There is no idle screw on the TB. That is a blade stop screw. If adjusted it can throw your TPS out of whack. Probably a good idea to put a volt meter on the TPS to make sure it is still within spec. Not saying this will solve your issues, but it's one less thing to look into.

He says in the first post Slotted TPS that would make me believe he already adjusted the TPS to the correct value, Plus that is not even what he is asking about nor would it cause his issue.

I also am thinking you CTS is BAD, you can ohm it out or watch live data on a scanner to confirm this.
