Diet soda IIRC has aspartic acid (Aspartame is made of aspartic acid and phenylalanine) which breaks down into methyl alcohol, then gets metabolized to formaldehyde. :eek: I'd not drink even one or two of those.. no sir, but four cases is almost 50 cans!! Wowzer, wowzer! Go ahead and search...

The canister is easy to remove with one bolt threaded upward on the aft inboard side. As you can see from the pressure readings, we've determined in the AF forum that the fuel pump is weak. Not only that.. the seal around the fuel pump is leaking. That would explain the smell of fuel from LR...

Yeah.. I got into the left rear wheel well over the weekend to see if there were any 'crisp' hoses, etc. Everything is original and whole fuel system should probably be gone through. I'd really like to drop the fuel tank and change ANYTHING that is deteriorated. What causes the FP gauge to...

What are the Fuel Pressure and Vacuum specs for a 3800 Series II (97 Buick Riv) for SC and NA engines? How stable should the fuel pressure be? steady on the gauge, or jittery gauge needle? Thanks, -Ed

Video of the Fuel Pressure start-up test is pasted below (12.2 MB) http://home.comcast.net/~edwinn/97_Riv_FP_startup.mp4 What do you think about that? Is it normal for the gauge to `jitter´ like it's doing? Notice the pressure goes LOW right after the engine starts, then is constant, then...

I bought an Actron #CP7818 FPT Kit. Not a bad unit! Here are some Fuel Pressure test results from yesterday Nov 11, 2013. Fuel Pressure (PSI) Trial Ignition Engine FPR Vac Engine After Num On Start pulled OFF 5-min...

Was able to do a warn start-up in the garage yesterday with hood open, driver door open with observer Ms Carol standing behind the car. I clearly heard (from under hood and exhaust pipes) the RPM stumbling, and roughness for 3 - 5 sec before it smoothed out. No smoke at all was seen by observer...

Yeah.. the vap canister is directly behind the LR wheelhouse (the wheelhouse closeout panel that is.) You can just about see the fuel filler pipe and vent tube on far LEFT of pic, going inboard thru the fender well opening. That's it right above the LR muffler. You can look through from the...

Lol.. Carol and I will go out shopping this weekend. Yeah if you go into a grocery store for a half dozen items, then come out and start it, THAT'S when the idle gets rough.. only for a ~5 sec but it sucks! Just going into the package store for a six-pack.. is enough time for a 'rough idle'...

How hold it Earl, let's not get frustrated. :cool: I see you've posted a LOT of stuff, and I did take seriously the 'black smoke' but I don't think smoke has EVER come out the exhaust of the Riv, but took an action item. How would one check for a dribbling injector (presumed into the cylinder?)...

Yeah I'm really new here and unfamiliar with the forums. The discussion thread was already moved from ET to GTBT. It's L36, see in orig post "97 Riviera - 139,795 miles - NS" or non supercharged. BTW i have the 3-Vol set of GM service manuals, but there's nothing like discussion with...

Not really too close.. why do you ask? -Ed

Wow.. that's a great reply! Here's my FPR, vac and fuel lines. It's pretty clean for a 97 w/140k. The topic is also posted in AF where one of the buds suggested to 'pull the Vac line and check if you smell fuel from the regulator port' but I didn't smell any fuel. The Buick Techs would...

I don't think there's any smoke. You mean out the exhaust? I'll have to get someone to start it and look. All of this happens without touching the accelerator pedal. It just starts to an unstable idle, stumbling for several seconds, then smooths out. There's a smell of fuel from the left rear...
