Thats what I was thinking of too, but it just seems kinda unlikely... ive thought about replacing injectors and coils before... its so simple just air, fuel, spark.... but at the same time its like a needle in a haystack.

Yep; this company is the real deal on injectors...also ensure you have no exhaust leaks around cats or anything & wiring to AFR sensors are in stock location.
May be a bit tricky to find, but you’ll get there.
Dealership only knows to hang parts.
You may ask on Forum of a good tuning shop for 370’s near where you live

jchammond · 05-20-2019, 03:54 AM

This place is very good & in driving distance...you may want to see who the Pennsylvania guy’s use.

Well I deff might have some exhaust leaks now since the minor accident lol.

I plan on getting a new catback system asap... just wanted to get it running as good as stock when i bought it before I start doing any power mods... But at this point I might just go for the mods and uprev and see if that fixes the issue in the process Lmao. Lol prob a dumb idea but im at witt end with possible options for this fix.

The 2 most popular aftermarket softwares for tuning are Ecutek & UpRev...not gonna say one is better than other,,,the tuner himself makes a huge difference.
Here’s a map of different shops near you.

I’m gonna relax a bit before kicking off my day,,,hopefully some of this information will help you along the way- as it may take a Performance shop to pinpoint exact problem with your Z & definitely afterwards a tune will boost performance over the oem...regardless of your amount of mods.

Thanks man! I emailed the shop near me

Ill probably just have them check it out and maybe even just go for a full tune session.

Ommateal · 05-20-2019, 11:13 PM

Well I talked to a guy at the tuning shop near by over message, all he tld me is he has and will tune Zs but doesnt have intimate experience with issues with them or diagnosing odd issues like mine....

Me: "uhh...oh...ok then...."

That’s no good; I’ll try & get one of the light tech’s at work to print me off some fuel information specs today/ as we used to have AllData & now Mitchell OnDemand,,,as with the variety of vehicles that the county has..they try & streamline some service information.
We definitely have everything offered for a Ford (IDS) & different generic stuff for other light vehicles.
I mostly use the J-Pro w/Cummins,Allison,International,Wabco,Volvo/Mack software + it has generic stuff for other Diesels

Flipping through some different pages; you may want to contact “Phunk” @CJMotorsports, as he’s stated the oem fuel pressure regulator is set at 52psi.
Your 30# didn’t even sound close when I seen it & that will cause many different issues.

My 2012 Roadster, bone stock, has been doing the same thing for about a year. After driving a while in the heat and shutting it down, on restart it acts exactly like a vapor lock. Fuel starvation is what I'm guessing. It happens mostly on super hot days. Living here in N. CA it's not uncommon to have 102 - 105* days. Mine's at the dealer's shop right now. I'll let you know what they come up with.
