Hi,
No problem, happy to help you work this out. More details on the table, easier for expedited answers..Believe CCRM’s OK, prime occurs normally, engine doesn’t cut out, fans operate- correct? Then, so far, so good.. Grounds can wreak absolute havoc...
Code 327 is covered, below. Let’s dig in..
-How are you clearing Codes? Jumper on DX Connector, Obd-1 Scan-tool?
-Any other characteristics re: how she’s running, Hot, Cold, rough idle, hesitations, break up at RPM’s, others?
-When this began- what were the first signs.. things occur suddenly..over time?
-Any recently performed work, or aftermarket parts installed?
Any spark knock or ping under a load?
Do any issues manifest with heat, whether high outdoor temps, engine temp, different or less when cool?
The above answered in basic form will go a loooong way.!
Start with the item’s below to establish a baseline, paying closer attention to listed specifics .Do nce over, Pull the Plugs, something needs replacing, do it.
Will help now & later, you’ll automatically check what’s around you. That’ll help. A “Tune-up” , but only running the motions, unless obvious issues turn up.. Read/Clean Plugs, oil change if needed. Grab a can of CRC MAF Cleaner, AntiSeize packet for Plug threads. Dielectric grease for Connectors
You’ll be firing this between cleaning, resetting Codes, but you’ll locate the issue. & others that were on their way..
1) Clean your MAF & ACT (IAC) w/CRC MAF cleaner.
2) Run a CAI? Regardless, Check your Intake Connections for vacuum leaks & run through all the lines & Filter.
3) Verify the
fuel pressure regulator is functioning correctly, Test Pressure with at the Schrader Valve. 30-40lbs, note the change with Reg. Disconnected....
4) Pull & clean out the EGR, ensure it’s properly operating, not sticking; evidence of the same. If it’s now cycling, check it, connections, the wiring associated with, Grounds.
5) With a VOM, Verify 4-6 Volts exists at the EGR Sensor, Both KOEO, Check Voltage at the TPS, Ground Blk lead, Red lead to Green wire- should be (0.75-98.DCV). Ensure your Plugs connect solidly. If a tab is broken- on any connector- replace it. Inexpensive Insurance.
6) Check your Salt & Pepper shaker Plugs for moisture free, Clean, low Resistance connections. Add Silicone Dielectric Grease to improve connections, inhibit corrosion, keep out moisuture.
Just an FYI: Q- Dizzy Stock or aftermarket? 94’-95’s appear to have OE Dizzy issues., i’d Relocated a TFI on a Well mounted Heat-Sink as one 95’ GT 302 I’d built w/ Broxix Hñ
Temp. margin of safety is non-existent.. After that, 3-4 94/5’s had 3+ TFI’s a YEAR.going & did the same relocate, Works excellent..
PIP’s are also vulnerable to early failure. Take a peek at things, clean anything up inside, blast the bowl clean with CRC MAF Cleaner.
.-I’ll adjust the list in terms of priority once I have that additional info from you-K?
Good luck!
