Sorry for the lack of pics but I wanted to get the job done asap. I did valve cover gaskets, battery service and wiper blades today on a 2008 4Runner 4.0. Pretty straight forward and not too bad to do except for one thing. At the back of the upper intake plenum, in front of firewall, there is a support clip that is attached with a 10mm head bolt and there is a hose and clip and a wire loom that attach at this clip, above and below. It is a real PITA to get in there to remove the bolt to release the clip, plus reattach the clip when reassemble. The rest is not bad. Lots more components to remove on the d/s. All the work took me 3.5 hours. The owner is the manager at my favorite taco Tuesday and taco Thursday bar. Have been going in there for over 12 years. By the way, 125k miles and in great shape, thanks to me.

My girl's 2002 TrailBlazer story for today:

My girl was on her way to Wa. this morning and got about 30 minutes away and experienced the CEL flashed 3 times and then stayed out and could hear a very dull pop top noise in engine compartment. She called and headed home. Off she goes in her 1990 K2500 ext cab pickup with 130k miles.

The TB has 75k miles on it. I checked for code(s) and got P0300. I drove it and experienced no problems. Plugs only about 3k miles old and I removed them and they looked like new and so did the OE ignition coils and boots-that were done when I did the plugs. Before that I tapped in at the fuel filter and found good fuel pressure at 54 psi running and throttling. When I had done the plugs, I had replaced the fuel filter and did replace the fuel pressure regulator when I noticed a leak.

Ok, I know I have a problem that is effecting more than one cylinder. I did some research and found that a known weak spot is the VVT solenoid. My shop owner friend allows me to buy parts on his account at a local wholesale warehouse. I wanted a Genuine GM solenoid, 12615873, but was not available. I bought a Standard Motor Parts VVT102 for just under $38 and over the years I have had decent results with Standard. Unbolted the P/S pump and flopped out of the way and changed the solenoid. Reassembled all components and it fired right up. I had already cleared the P0300 code. I went to live info on my scanner and all looked good and drove it slow in neighborhood, 35-40 on major side streets and at 60-65 on the highway and romped on it hard a couple times and am still impressed with that 4.2 engine power. No code(s) came back and will be driving it more while my girl is gone for a couple days.

Almost forgot. I plan on cleaning the MAF sensor tomorrow and inspecting the MAP sensor.

So, knowing all this and what I did, what are thoughts of the members here? Thanks in advance for input.

I have questions on this subject, on my '07 Escalade [6.2].

Do you mind? And, if not, should I ask here or start a thread?
