  1. Yes at 72 n up there is a deep bass noise that sounds like a hub when str8. I did say both wheels where in the air???? I check bearing by hand and it did seem to have play. Idk two lane other then this. There might be a small flat spot but I can feel it in car. The low track light pops on when turn sitting still
  2. Put the car up in the air and put her in drive lol. Funny thing is one tire spun and other didnt. It cool to see I differential in action. ( wish it was limited slip) . But to the point found the bearing. It wobbles. Not side to side but rather up and down. How you all figure that is?
  3. I an thinking one of the front wheel bearings however I'm having trouble find it. Symptoms are when sitting still turning the wheels the low traction light comes on. No other lights ie ABS. I know the normal things to check. The plug on the speed sensors. The bearings seem fine I don't hear the humming or tire noises at speed. If I Jack car up there is no play any direction nor do I feel any grabbing feeling or drying out sounds in the wheel hub. Any other way to check them
  4. Happy new year u all. Thanks for all the help and ideas. You all are great .. Forever Pontiac forever. Had to go there hahaha
  5. Would iridium's be better in my case .... frosty got a question. Does it really hurt to over gap a plug? I miss read the book and it said .05 I set them for .06 I reset the plugs gap from .06 to .05 and removed anti-seize from nickle plated plugs .. then was like what the hell and actually read the dielectric grease packet (n this is why u should read all manuals) turns out it is an insulator and not a conductor ... cleaned up that mess and the difference in gas mileage is crazy. I do think this is why I though the old plugs where bad to start with. Damn dielectric grease on contact points
  6. The book in the car said platinum plugs and then I go for cheapest cuz I'm poor 😥 lol. I was wondering if they where getting a little to hot myself. I changed them cuz I just change plugs like ever 30k ish
  7. Hello, nice car btw. Like frost said what have u done to it
  8. Got some NGK spark plugs that ran well for about 35,000 miles or so. When I installed them I put new boots on (GAs spark plug wire set) with dielectric grease. The plugs came out very dry so I put anti-seize on the new ones and worked it in also dielectric grease on them as well. Here r some pics of old ones. Any advise about this?
  9. If by make sure to replace intake manifold gasket they get leaks often if ur getting a milkshake
  10. Or is it perfectly normal sounding engine for the miles and I might have a little PTSD from cars leaving me on the side of the road. Witch btw 2 of 4 where Ford Tauruses, one was a Mazda 323 I burned up clutch and last was a 1995 Grand am 2.3 ouad 4 witch had problems lots witch showed it's colors after I redlined it at like 99mph maybe faster and caused rod knock. The oil light would flicker at idle on the way home. (This story is the car to the grave) witch was 80 to 90 miles ... It was horrible loud it finally locked up 3 miles from home. It wouldn't even turn over. O and mind the water pump also when out on the way and stopped by two creeks to fill up radiator lol. The oil was changed two days before and was dark gray when it died. Opened oil filter and found no shavings or specks of metal that I could see. There was a fair amount of dirt however so yeah. That o2 was the upstream one changed it two month ago w downstream
  11. Found a good reason the rear left tire was messing up. Wheel hub/bearing was cockeyed and also bearing itself was wearing and drying out. The tire on RL would always look like locked up the breaks on the inside at just one spot and the rest was fine. So I guess it wobbled in motion. The hub had very little play when i changed it. Thank you all for your help and input. More to follow, over and out!
  12. So here we go again. Lol 2000 Pontiac Grand am 2.4l 243,xxx miles. So as we know the car sat for a wile it was run for a wile with 2 cyls working and two getting fuel. Possible cylinder walls washed and over heated. I think we have piston slap got a few vids of before and after oil change. First vid is old oil second is engine after third is before oil change. If you can hear the second video you can hear the sound well it is under the lifter tick sounds ... Can also see the glitter in the oil pan I think ?!?!?!?! ...... thanks you-all for the input and help. The whirling nosie is the alt btw 20181207_004144.mp4 20181207_003940.mp4 20181206_142218.mp4
  13. Now I'm hearing a hollowed muffled almost bell like sound. It sounds the same cold or hot. When I first started the car in the morning I don't hear no chatter or anything. I'll try to get a vid of the sound.
  14. My grand am uses a door flap with electric motor ( temp selector ) make sure that is in working order to
  15. Cool thanks people. Frosty that confirms the thought this car sat for awile. Center part is in-between the two breaking contact point. They didn't look that bad when I had taken them off the car btw. The contact point was clean but pitted and grooved
  16. Is thermostat bad or maybe it didn't seat correctly when installed. It's happened to me before. Like to much cold water going through. Maybe try a hotter thermostat????
  17. Yeah I left them in the rain a few days for I took the pic or are you talking about the center of them? I do think the car sat for like a year n half ... And change the oil was first on list lol.
  18. So just replaced some parts they where shot. Makes me wonder what the heck hell these parts suffered. Lol. The caliper on driver's side was so bad it broke my c-clamp. Had to undo brake line and beat the heck out of it with 🔨 untill it worked. Wound up replacing however! There was a feeling of unblanced tire magically it when away lol.... Anything else or tips I should know or do anything thing else? 😂😂😂😂 Look at that rotor 👇👇👇👇🙃🙃🙃🙃 dang cat 🤣🤣🤣🤣
  19. Yep like u so said. Tie rods where shot and bushing .... Car now turns scary sharp. This whole time I thought the car had great handling well come to find out it didn't. Next up ball joints and a wheel bearing or two. Question the oil when I drained it had like a glitter look. Not bad just like I could tell there was metal wear ... No flakes no large pieces oil was still amber on the stick. I had to look closely with a bright flashlight to see what was in there anyway. What do u all think? 20181121_203105.mp4
  20. Well I think I found the problem! I filled up the gas tank to the max for the first time finally and then smelled gas like crazy strong. Twas like da hell. Yep there is a hole in top the tank where the fill neck connects. Bet 100% that I'm getting water in there.
  21. I've been using marvel mystery oil for two tanks now and it doesn't miss a beat. The only other thing I did has been take throttle body off and made it spotless. From what I could tell one of the vac line in the body was plugged the EGR solenoid
  22. Yes the coil are very different in the readings. The one I replaced that was dead was 30k the new one is 10k the one from pull a parts is 6k
