*A vacuum line smoke test exposed multiple splits and damage in MAF to TB intake tubing. Once the tubing was patched, shifting returned to normal. I'll test drive a few more days before declaring the issue "SOLVED" Thanks again to EVERYONE!!

ISO new/usable intake hose (the one that connects throttle body to MAF box. Ideally, hose+ rubber. I've searched site, ebay, Amazon, etc. etc. Any 2024 sources for these?? THANKS! .cd

Hello All and, as always, thank-you for the support!! I would like to replace the broken connector GOING TO my idle control valve. Is there a popular and reliable source for new connectors for the ICV and other 94 Explorer gadgetry? Way too many of my connectors are broken and brittle. I...

ANOTHER CLUE: first time night driving since the gasket surgery and I noticed another oddity... Upper speedometer dash lights slowly faded out from about the 35 mph to 55 mph area. I had a bump in the road and the lights returned to normal brightness... Guessing I'm dealing with an electrical...

Thank-you, again 410Fortune! If I have any energy left after work today, I will dig deeper into the tube/line mystery!! TY!!

I see rubber vacuum line from the vacuum tree that moves toward the middle of the firewall and attaches to a metal tube that drops straight down toward the ground. ... Might that lead to the modulator (The modulator that my mechanic says I don't have)?

Thank-you, much!!!

Hello, Just had major intake work done to fix coolant leak. Now the auto trans does not go in to highest gear (overdrive). I suspect a vacuum hose or such, but have you got any ideas to get me started? If not, back to the mechanic we go. Best!! .cd

Very Nice all!! BTW anybody else getting 37 pop-up ads when trying to view pix?? Best! cd

TY!!

TY! Is this the speedometer parts down in/on the automatic transmission?? If so, is there any easy way to locate it?? I may attempt to fix my annual "cold weather-only" speedo "bounce"... Have read for years that some ?gear? needs to be cleaned/lubed *somewhere* on/in auto transmission. Best! CD

Hello All Is there an upgrade to the factory center AKA Cyclops brake light assembly or even bulb upgrades, please? Ideally, I would install a drop-in replacement assembly that flashes red before going solid red. ...sort of like what some motorcycles have. Thanks! .daniel

Would like to increase turn signal rate. I know there is an (old style) metal strip "relay" that I can remove/replace under my dash. Would anyone happen to know if these quasi "relays" are sold by speed/duration, etc? Or, maybe if I modify the existing metal strip I can manipulate pulse speed...

any chance someone installed plug wires incorrectly creating a firing order problem?

Not compression but run/rich 2 cents ICYI. Last fall my EX would run rough for just about TWO MINUTES or so when "cold"; drivable but rough and wrong BUT ONLY for about two minutes!! Turns out there was excessive crud in one or (?) two coil "holes". ..crud rotted a plug wire at the coil...

When you unscrew gas cap is there a hiss indicating system pressure???? If not, there is a gizmo under the upper intake that may need attention. It may be called purge solenoid-not sure. Good luck!

Welcome! I'm far from an expert, but my first thought: too much air. I would double check snorkel connection, that one inch hose related to snorkel and listen for vacuum leaks. Best of luck!

Nice! Thank-you! Did you find a cure for the low MPG?? My 94 gets about 15 mpg overall. Any help appreciated!

Hey All! First I appreciate all of the help with my many recent "tickets"- thank-you! This recent adventure began with rough/rich idle and sub 11 mpg. I then replaced DPFE and MAF sensor and truck is running much, much better -but... Codes are still available if I go looking for them...

UPDATE: I hope this doesn't jinx the situation, but I installed new DPFE and have no CEL illuminated.

Thanks for asking. New codes: 157, 332, 558.

UPDATE: New MAF sensor installed. Engine no longer running rich, no longer throwing 158, 336 or 185 code but have new/different CEL codes. ---558, 332 and maybe 157 -still checking

UPDATE: New MAF sensor installed. Engine no longer running rich, but have new/different CEL codes.
