Hi Paul,
Hope you’re doing well.
I’m comfortable with and enter all help threads, categories, topics, 60’s to 2016, 4Cyl, I-6, V6, V8 Cyl, Carb, EFI, F.I. I do look at issues people may prevent one from getting to work, hurting the.car- quickly, to save them some money from taking it to a shop, but helping others how I can is why I do it.
I’d realized your car wasn’t an SN95, 2nd Text, V-6 to V-8 control systems, returnless fuel systems, sensors operate much the same.
Soo, the connector I’d noted was expanded slightly, and corroded on the FPRS, looks like possibly that blue Maybe a chemical used in attempt to improve the connection? Is the connector plug retainer snapped to snap the 2 together, or is it OK?
Almost looks like blue loctite, lol. As pictured, there’s significant corrosion on that middle upper female connector, were you able to remove it? If you have a needle file, you could remove that and expose the surface underneath.
A few flat passes with flat blade x-acto razors gently, not gouging (media is not going to enter the fuel rail).,Anti corrosive will help, along with slightly bending to ensure no intermittent connection.
Are you still getting any CEL’s or CPU codes with your Scantool? I’’d think your fuel pressure/rail codes are gone,
Are you running a CAI? Either way I’d do a quick test of how tight everything beyond the MAF is, every intake line and the intake Tube connections, themselves. Just a quick run through of any unmonitored MAF air making its way in.
Can you do a text sheet readout, rather than a graph) of how it’s running now, & are you able to do a drive cycle, whereas if a CEal pops it’ll log all the info before and after, it’ll show what caused the CEL to trigger.
If that’s not possible, I’ll delve into this later today, near 4AM, wanted to
ask about codes
1) How does the motor run when you note an issue as described? It’s intermittent, 2) DIDNT occur last time you drove it- how does the motor react?
3) Can you do a drive cycle monitor, if so, that anomaly described will show. the anomaly you’re picking up.
4) Does the motor have the power it always did, any hesitation, last full tank cycle of fuel, when was any added last? Run the highest octane you have, I.e. 93, or 91.
5) When you click for leaks in the intake, spray the butterfly (CRC) if it’s carbonized, and it’s bore.
6) Car Idle smoothly, any vibration in the steering wheel, or sitting in to 2,500Rpm’s
7) Air filter cleaned recently? If a reusable
K&N, was it re-oiled?
(Ok, i’ll read the other info when you type it up, make a solid plan from there for the most useful testing I can view, need it under a load,. What do you have for Scantools, and are you running a Tune of any kind over the OEM program?.
Tall to you later, keep in mind. there’s a time period that the CPU may take a bit to relearn.
Talk to you later-k? Good luck!
P.S. See if you may perform a drive
cycle test, or a ‘snapshot’.
Can you snap a pic of the motor? 1 passenger engine side front to back, another from the drivers side. If you can, it’ll make things a bit easier.
Take care!
John
