Full Tune

Im starting a full tune-up on the Taco today. I'm replacing the plugs (Using Denso), the boots and springs, the PCV valve, air filter, cabin air filter, oil & filter, and cleaning the wire harness plugs with electrical contact spray and lubing the jackets with a bit of dialectic grease. At 142K its time for another round of this type of maintenance. I do have a question for anyone who is interested, how often do you replace the ignition coils? I am going to clean them and do an ohms test but that wont show me specs under a load. Just curious.....

Update: Well all of that went well, started cleaning the grime off my headlights lenses, the just ordered new ones from Rock Auto (DEPO) for 54 a side. They came with new LED bulbs installed. Also ordered tires, LT 265/75 R16, new Billsteins front and back and new inner and outer tie rod ends. I imagine there will be a few additional front suspension parts to get but this is a good start I think.....

Question: would this little truck (2.7) 2wd pull a motorcycle (cruiser) on a somewhat light trailer okay? Bike weighs 900 (est) and the trailer 800 lbs. so 1,700. I realize the capacity is 3,500 but I have hauled enough to know not to trust that number. Im talking a trip of 500 miles each way. My guess is no, too hard on the tranny but thought I would ask, my Jeep has the power but also cant miss a gas station.

 

When you replace the PCV valve, you should also replace the grommet and probably the vacuum line as well (along with all the vacuum lines). The grommet is going to crumble to bits when you try to take it out, have a plan to try to avoid it and to be able to fish /vacuum out anything that might try to fall down in the valve cover.

You don't have a cabin air filter.

Not sure which harnesses you're going to clean, but in general, I wouldn't screw with things unless I had a reason to. Like if my 4wd isn't working, it's worth checking the harnesses and connectors going to those actuators. Otherwise, you're just risking introducing a new electrical daemon in your truck.

Not sure what lubing the jackets is about. I put a little dielectric grease on the battery terminals after I've made the connections and tightened everything down.

@150k still on original coils. I wouldn't change them unless one was malfunctioning (as indicated by a misfire).

 

My coils started giving me issues at 160k. Had them replaced with Denso coils and no issues since.

 

Didnt mention what year you have......
2001 and up dont have pvc grommet...they screw in...

As far as coils ...the coil over plugs dont last nearly as long as the old fashion ones....
so those started in 2001?........

As far as connectors......get a can of de-ox.....

For real?

I never checked my 2004. But I just searched a Youtube video that shows it's the grommet/pressure fitted PCV found on my 1998.

 

Yeah if you're like me and have the rubber grommet one...
replace it once a year .....so you dont have to go fishing for the lower part when it breaks off in your head....

massive vac leak when that grommet breaks off....and its invisible......

and use the doorman one.....some like the napa's are a hard rubber.....and are the devil to get out.....

 

My 2001 3.4l does not have a screw in PCV valve. It has a grommet and press in valve. Not sure which motor the OP has.

Replacing the grommet once a year is excessive.

 

My 2.7 is the 2TR-FE. The PCV valve threads in and has an o-ring attached. I started with a new Standard American PCV valve, the thing was so brittle it literally crumbled under little tension. I got the old threads out with an easy out and replace it with an OEM valve, much better. No, it was not an issue, I just wanted to replace it mostly to feel better about it... for what that's worth, but in doing so, found a crack in the short hose that connects to it so replaced that.
