Here's one for ya, 2002 Pontiac Bonneville SSEI, just got
2002 Pontiac Bonneville SSEI, just got the car old owners had enough, I have 300 and 463 codes and 463 is tank is empty gas gauge bounces full empty half, anyways, car starts like a new one, has a very light tick was a lot worse when I first got it, I have installed new plugs Ac delco 41-902 & wires, didn't do anything and two plugs were cracked one badly, back to symptoms, I can rev it up to 3,000rpm and sounds awesome running great but anything past that sounds like engine is gonna explode, also absolutely"no" power when in gear can't get it to rev past 2,000 rpm that is no joke , gotta baby it ever so gently to get to 45-55 and that's after two miles or more, car has 153k on it owner said his daughter took it to school on way home acting up next morning run good till after school and is where it is now, I have squirted water listening for air leaks, sprayed carb cleaner over entire thing and used propane so I'm ruling out vacuum leak, I have an in line spark checker you just lay on wire and shows spark and now seems great , to no effect , pulled egr off made a block off plate for it just to see and that had zero effect, I had cleared codes once before and it had 403 code meaning egr open or shut I cleaned it looked like someone been here already, next game plan is fuel filter then pressure, exhaust is eye burning to say the least so really don't think this is it, catalytic is another story, from the tip of outside cat its 300+ but 8-12 " inches from opening it drops over a hundred degrees sometimes 150 degrees (have a temp checker) basically there's 18inches of pipe between cat and half muffler looking thing and temps going into muffler barely at 100 degrees, beat the hell out of it but sounds hollow one small chunk rolling around but isn't very big by sounds of it and will bounces back to cat while running so I think it isn't what's possible to plug it, very little exhaust coming out pipe though...Gonna pop a couple holes in it to see anyways, any help would be swell!?… read more
