    1997 1FZ Hiccupy idle and running rich

    I’d guess the OP gave up on chasing the ghost and sold the rig. Some of these old trucks just don’t have a perfect idle. It’s not a perfect world.

    For those who dropped to one Cat……

    Checked fuel trims with an Ultragauge. Simple plug-in device that displays a vehicles engine temp, RPMs, etc. not sure how accurate it is for fuel trim readings.

    For those who dropped to one Cat……

    I don’t think my Magnaflow has any brand markings on it aside from the box, but it’s been a couple years since I installed mine.

    For those who dropped to one Cat……

    Yes, I went from 2 cats to the Magnaflow downpipe with 1 cat on my 97- seems hotter after single cat. I still have the heat shield in place, as well. What ST and LT fuel trim readings are you seeing at idle and on the highway?

    Amayama parts ordering status messages and what they mean

    I’ve had pretty good luck with Amayama and Partsouq. Partsouq is fast delivery to Midwest US- about a week average from the orders I’ve placed. Not as fast as Amazon, but pretty darn good by pre-Amazon standards.

    Help identifying something on y-pipe/cat

    If you don’t mind my asking, what kind of fuel trims are you seeing in closed loop and what device are you using to monitor them?

    Amayama parts ordering status messages and what they mean

    I think it means “please wait a few days while we wait for supplier to inform us the item you ordered has been discontinued and is no longer available.”

    Vac hose question

    Looks like I can rule out vacuum leaks… It stays dead steady right here at idle.

    Vac hose question

    I’m looking over the vac hoses on my 97LX. I’ve got a thicker vac hose (off the front of the VCV) under the upper plenum that I plan to replace. Aside from that the other hoses look fresh and OK. However, while some of the smaller hoses are the OEM (all the small ones under upper plenum...

    Changing a vacuum line under the upper intake

    Thank you. I didn’t know these existed. Just bought a set.

    Changing a vacuum line under the upper intake

    10-4, my friend. Sounds like I need some lube.

    Changing a vacuum line under the upper intake

    I’m thinking about replacing a vacuum line under my upper intake. It’s the thicker line that runs out of the front of the blue VSV and does a quick 90 degree before it goes into the throttle body. I don’t want to remove upper intake. It looks like I can remove the black steel bracket that...

    Fuel Trim

    Yep, cleaned old MAF w/ no change. Tried a new OEM MAF and no change. Today, she’s idling around 8% LTFT and about the same / maybe a little higher on the higway. She’s happy today.

    Fuel Trim

    Gotcha. Thank you. Would you keep digging to try to figure out why LTFT is always around +10 or call it good?

    Fuel Trim

    Thanks, Landtank. So you see +10% LTFT as normal on these trucks with 33” tires and heavy aftermarket bumpers?

    Fuel Trim

    In partsouq diagram lookup looks like it’s called a fuel vent hose, which makes sense to me since it runs to charcoal canister. Wondering if this old vent hose could cause a fuel starvation problem or a vac leak?

    Fuel Trim

    I did find what looks like a thicker vacuum line under the upper intake that looks original and crusty. Pretty disappointed b/c I paid a mechanic to pull intake about a year ago and he agreed to replace all the vacuum lines while under there. I’ll post a pic of the vac line- it runs off the...

    Fuel Trim

    Not sure. It’s been like this quite awhile.

    Fuel Trim

    Thanks. Also, I know ethanol blended fuel (which I use) plays a part in the LTFT. Maybe also the 33” tires I’m running?
