Still looking at the rough idle on cold start

I had an opportunity to hook up the AFR meter today, but then I realized that I would have to remove a working O2 sensor to do it. That won't work so that plan was cancelled. I also fired up my AutoTap app on my laptop. It's a longshot, but AutoTap can read and log info from the OBDII port. So now I...

Re: 1965 Oldsmobile 442

Did the console already have accommodations for installing the gauge?

Re: 1996 Collector Edition Corvette

ODO: 104412 From recent driving experience in the heat of summer, I've decided to chalk up this "hot start" issue to alky fuel vaporization and move on. I added some insulation to the fuel lines that are exposed to the heat of the exhaust manifold. Heat shield2 (Medium).JPG I don't know ho...

Re: 2008 Trailblazer SS

Today, I was finally forced to tackle the AC leak. The outside temperature has been hovering in the mid-90's for many days. I had in stock the needed AC low pressure line to replace the leaking one. The job wasn't really all that bad. Once the new line was hooked up, I evacuated the system and it he...

Re: 2008 Trailblazer SS

ODO: 133522 Just as a followup on the previous post about the whistle when applying the brakes, it appears to be temperature related. Likely a problem in the vacuum booster. It will have to wait until it gets more annoying. Its summer now and the problem disappears. Yesterday, I corrected a problem ...

Definitely not moving the way it should (like mine does).

Re: 1996 Collector Edition Corvette

Nope. The entire fuel system was cleaned, flushed and new injectors were installed just after I got it. It was job 1. I've changed the fuel filter about 3 times now and cut them open. Very little to see inside. I went out to do some testing about 1.5 hours ago. Once it got hot (197°), I came home an...

Re: 1996 Collector Edition Corvette

Well, here's the thing...there is a history related to the hot start issue, but the facts are muddied by other issues going on at the same time (fuel pump problems and changes). Right now things have settled down enough to allow me to concentrate on only these two matters. Consequently, I don't have...

Re: 1996 Collector Edition Corvette

Yes. It happened with the second Delphi pump and now the Walbro pump. Thanks, Andy, you may have something there. I can try shielding the lines closest to the exhaust manifold to see if it changes anything

Re: 1996 Collector Edition Corvette

Although Silvia is now running the best since her rescue from the barn, there are still issues that need attention: 1. She is cold natured. On the first start of the day, it starts quickly but then idles rough. She smooths out when up to temperature. I'm going to remove, clean, and adjust the Idle A...

Re: 1996 Collector Edition Corvette

ODO: 104223 I put on 55 miles and Silvia's Climate Control system appears to be working splendidly. I set it to 70° this afternoon and drove around in with the ambient temperature at 88°. The system kept me comfortable with the windows and top up. I hope it continues like this. It felt very civilize...

Re: 1996 Collector Edition Corvette

We can always hope. I think Silvia is going to have to prove her reliability to Randi before I get a traveling companion. It occurred to me that it's possible that some of the younger dudes in our group may not be aware of the Lone Ranger western series on the radio and later TV starting in the late...

Re: 1996 Collector Edition Corvette

ODO: 104168 For the last several days I've been actively working on several things simultaneously. First, the fuel pump. I took another dive into the fuel tank to replace the small piece of standard FI hose attached to the fuel pump. The new hose is immersible in fuel. While I was in there, I decide...

Re: 1987 Corvette Z52

Be sure to check carefully for evidence of movement at the front and rear attachment points of the C beam that Andy just mentioned. It's not uncommon on C4s, for the two ends of the C beam to loosen a little over time.

Re: 1996 Collector Edition Corvette

I went to NAPA and bought some "fuel injection Hose". It was about $8 a foot. It seemed quite expensive, but I needed it. When I got home, for some reason, I started researching the hose I bought. I quickly learned that this hose is not to be used for "in tank" applications. What...
