Being light on the gas pedal has a dramatic impact IMHO. On a recent highway trip with my son, I pointed out my avg while driving was 18.8; his was 16.2 over similar roads/elevation. Like all teens, he loves to “step on the gas” and brake hard, even when unnecessary. I challenged him to beat my...

Was definitely something wonky with TT plugs. The gaps were clearly off, as noted above. Exchanging the TTs for SKs (from the same Advance Auto), fixed it. Gaps on the SKs were right on. TT packaging looked OEM, no paper electrode covers or anything like that. Appeared to be exactly like...

Update: I went back to SK20R11s. Issue solved. I’m back at 13 mph in city traffic driving and 15 mpg in the burbs. 19 mpg at 70 mph cruising.

Agreed - on my ‘03 I get 19mpg at 60 mph, 18mpg at 70 mph, and 16-17 mpg at 75-80.

Mine’s pretty rusty, too, though not as bad. It runs like a champ. Have been able to get all undercarriage maintenance chores done without issue. I’ll get another 5-7 years out of her. Then find a nice, clean southern one 😊

I can confirm the Amazon-purchased coils are 100% authentic and work great. FYI, Amazon limits the number of coils you can order to 6. Had to log in via my wife's account to get the other two ;). Silly.

Denso spec’s the IK20TT as compatible (at least from their website and automotive stores). A number of guys are putting them in 2UZs and reporting good performance. I thought I’d try ‘em, but am now second-guessing that decision.

Cleaned MAF today, which looked good pre-clean. Now it’s extra clean. ;) I also pulled a plug (#2) to inspect and check gap. New plugs are Denso Iridium IK20TT. To my surprise (?) the plug gap was 0.85-0.90mm, not 1.0 mm as spec’d on the Denso site. Some were as low as 0.80 mm. Could this be...

@suprarx7nut- I’ll definitely look at bank1 vs bank 2numbers. For MPG I’m looking at the trip averages and the tank-since-fill average. The ScanGauge tank average agrees with the built-in display, so I think the numbers are accurate. I’ve also noticed the fuel needle dropping much more quickly.

Thank you! I’ll pull it back apart and do a spot check on a few plug gaps. Are there any Techstream metrics that might provide a clue?

Hi - I have a '03 LC with 182,000. As part of PM, I did a full coil (Denso 6731303) and plug (Denso Iridium TT, IK20TT) replacement for all 8 cylinders. The engine starts up and runs beautifully. Purrs like a kitten. No noises or oddities whatsoever. However, my "city" gas mileage has fallen...

Thanks, abuck99! So the widening "seams" that run lengthwise down the coil are cracks, correct? The truck has 182,000. PO had plugs changed at 105,000 when TB was done. I suppose it's time. Nice $$ find on the Denso site. Autozone, Napa, etc. are at least double. o_O

Replacing plugs on a '03 LC. Did the (easy) passenger side first. Two of them are definitely cracked. The others look like a seam from the manufacturing process is widening. Pics below. Looking for guidance on which ones should be replaced. Has anyone had success with non-Denso aftermarket...

Sounds and looks like a phenomenal trip!!

Thanks, clayinho. The sensor on the passenger side, which is way more difficult to access, was actually easier. Go figure. A flex head ratchet is a must for this job,
