Now just gotta figure this out smgdh-
man I'm so perplexed and just you know I'm trying to figure out some things before I go and get the tune check and changed. I've tried a lot of things recently and tomorrow I may even unplug the chip to see if that will solve the issue I am having of and it's not a startup issue idling crazy or anything like that when cold or nothing like that my issue is just in the summertime and the car gets up to about 190°, after I shut the car off when I go to start it back it will start fine even though in extreme hot weather it will sound sort of like it it doesn't crank up as strong as it normally does, but it will kind of sort of sound like it's too much fuel at the startup or something almost like a flooding situation but it will start up fine all the time.
It will idle fine for about 20 seconds and depending on how hot the weather is it will sometimes it will you can see the RPMs going to go up just a little bit you'll come right back down to the same spot and idle for a little bit more and then eventually it will just cut off. If I tap the gas it will auto up the RPMs will go up of course and it will idle another well it will go up and then come back down to the original RPMs and then after that a few seconds that maybe 5 seconds or so it will cut off unless I play with the gas and until I get going it will do that. Once I start to drive off and if I can continue driving for up to some speeds up to about maybe 40 45 50 for a good minute or so it will be fine it won't do it again until I cut the car off again.
Everything checks out the TPS I've checked the range of the TPS it has a nice steady smooth flow from one volt to 5, tried a new idle air valve, fuel filter is new, a used distributor off my other car, used TFI module, a new ECT sensor, now I did fix the ECT connector since I had the tune actually rechecked in January and so I remember him saying something about the car was warm you knew the car was warm it's been running for a while but it was showing that it was still cold or something like that. So I'm hoping that's all it is is he needs to change the has someone said earlier in this post the startup fuel tables so I'm going to make sure I have a note of that for him so that he can have something to go by as in playing with and trying. I'm going to get there early that morning and I'm not leaving Columbia which is 2 hours away they close at 5:00 but if I have to stay all day trying and I'm sure he'll have different vehicles he'll be working on, but he'll just have to play with it all day if he has to to figure this damn thing out because it's a shame man it's it's been the same thing on the other car when the engine was in there and I'm sure I have a whole lot more things corrected and fixed and tried and checked this time around on this engine that is just perplexing man to still be doing the same damn thing pretty much. Does not do it in any other weather by the way I mean winter time spring fall the car does not have this issue. And the thing drives too strong and too good it does not have any kind of idle issues even in the summertime other than when I cut it off and start it back up. If startup fuel tables need tweaking would that be an issue only in summer though????
The injectors that I have are 20 something years old and they were used when I got them the 24 pounders in so I was even going to order some 36s because I'm going to do a 331 at some point either for this car or for the 95 and worst case is after he makes some changes and it still doesn't fix anything I may just go ahead before I leave there put those injectors in and let him go ahead and make the changes and see if it's a leaky injector. But if it's a leaky injector why isn't it doing it at any other time of the year or anything like that and they're definitely isn't any signs of any leaking you know any injector leaking on top of the intake or anything like that and also the fuel pressure it is holding a good fuel pressure very well and no smell of fumes in the vacuum line when I pull off regulator.
I will also take all of the things that I just bought even though I'm going to take them back to AutoZone but I'm going to take them anyway just in case he wants to try one of those on during the process of anything else that needs to be checked or tried the TFI module, the IAC, the ECT, and the distributor.
Change the fuel filter recently as well because I did not change it when I did the engine in 2021 when I put it in still no change and I'm sure if it was a fuel pump situation the car would act up and other normal regular situation as well. Should not be vapor locking from what I've read with newer cars and the fuel pumps PSI it should not be a situation where it's vapor locking even though the symptoms sound like you know yeah that could be a situation where the fuel is too hot or something like that but definitely should not be that.
