Regal :: 1989 Buick Making Grinding Noise When Accelerate
My 1989 Buick Regal is making a grinding sound when I accelerate. It makes the sound slightly when it's just idling as well, but it definitely gets worse when I start going. It's been dying a bunch too. The engine will just shut off. The scariest part though, is when I pop the hood and have a look, there are shards of metal that I can only assume have been ground off, thus the grinding noise. It's near the belt, but that's all I really know because I'm not car smart at all.
View 2 RepliesBuick - Regal :: Rough Idle Randomly And CEL Came On
I have a 1995 Buick Regal, with a 3.8L engine. When I start the car sometimes it rough idles and I have to give it a lot of gas and then it runs fine. This is completely random. Sometimes it runs just a little rough, other times really rough. The rough idling when starting the car happens about 1 out of 25 times. Sometimes when this happens I get a check engine light, most of the time not. When I am driving around I also will randomly get a check engine light, but I can't tell anything common to it. It has come on while braking, while coasting with foot off the gas and brake, normal city driving, highway driving. Also my CEL always turns off when I turn off the car and doesn't come back when I restart the car. Always.
I haven't been able to figure out what is wrong and since my car is transition OBD1 to OBD2 I can't use a OBD2 code scanner (it is an OBD1 port), nor will shorting the pins in my OBD1 type port give me codes. Being this the case I took it to a local mechanic and they scanned the computer and said they got 16 error codes. They reset the codes but couldn't get the CEL to come back on. I took it drove it for a couple of days the light came back on so I took it back to the shop and they got 18 codes out of it, but they were mostly different, with some of them giving the opposite readings of before (O2 sensor high one time, then low the next check). They said they didn't know what was going on but wanted 3-4 hours to diagnose the PCM (Powertrain control module) and would probably replace the PCM (~500 on top of the diagnostic fee). That was a bit much for me, so I took the car back.
The things I have checked are fuel pressure (seems fine at idle and revving the car in park)Vacuum is 19 and when I rev quick it drops to zero or so then up to 25 and slowly goes back to 19 (I think that means vacuum is ok). I put the gauge in the O2 sensor before the CAT and I didn't read any pressure, so I think the CAT is ok.I put on a new fuel pressure regulator, and a new fuel filter. I got the same PCM at a Pick-n-pull place and put it is my car 3 days ago. Yesterday I got a check engine light while driving again. The mechanic will charge me to check the codes, but I think it is just doing the same thing as always. I am sort of at a loss as what to do. I though it I was to dive around with a scanner hooked up and the light went on then I could see what the sensors were doing when all the trouble codes fire. I was looking at the Actron CP9190, but it doesn't log the data stream for OBD1 cars, only for OBD2.
Buick - Regal :: Idles Rough And Little Hang-up When It Shifts
My son is about to purchase his first car. A 98 Buick Park Regal. Feels like it idles rough, and has a little hang-up when it shifts. Seller claims it's due to needing a transmission mount replaced. Does this sound viable?

I own a 1996 Buick Regal with 132k miles on it, 3.1L six cylinder. The other day I was doing some general maintenance and noticed that the exhaust smelled like sulfur (rotten eggs). Now, I am loosely familiar with the causes of such a thing but not well enough to diagnose it properly the first time. The car has been idling rough since I got it (almost a year ago now), I have a feeling that it could be the O2 sensor causing the rough idle and the sulfur smell but I am not completely sure. I should have one of those fancy three-part injector cleaners done?
View 6 RepliesBuick - Regal :: Rough Idles And Misfires On Cold Starts
1991 Regal, 3800 v6.
So here's an interesting observation. When i turn the ignition to ON, I hear no sound nor feel any vibration from the fuel pump. Is there any scenario where a fuel pump fails to prime yet kicks into gear after a start? So, I've got rough idles and misfires on cold starts. Before I start replacing parts my diagnostic plans is as follows:
Remove and inspect spark plugs.
Inspect and test starter coil/distributor (still have to research how to do this)
Test resistance on fuel injectors.
Test pressure drop on fuel rails.
Test compression for possible small head leak.
I'm wondering, if I do have a tiny head leak that is letting in a drip or two of coolant after hours of the engine sitting, will I be able to see this on the gauge doing a compression test? I've never done one before and still need to buy a gauge, but maybe I'm better off just doing the other tests and if they all check out I can be certain it is a minor head leak.
My assumption is that I have a leaking injector; just trying to do things the proper way.
Regal :: Buick 1995 Shuddering / Rough Idle And Lack Of Response When Accelerate
I have a 95 Buick Regal, V6 3.8 Liter. The symptoms are the following: stuttering idle. And lack of response at times when I try to accelerate. Like sometimes I'll be driving on the highway, and having no problems. Then I'll be going up a hill at around 55 mph, and then the car will shudder as I try to maintain a speed of 55 mph. So I have to ease off the accelerator and slow down. At first I thought this was a transmission problem, but I am guessing it's the same problem that causes my choppy idle.
So I had this acceleration problem on the highway when I was going up a hill. And a weak idle. These problems have been going on for several months now. They were annoying, but didn't seem that serious. Then all of a sudden, on a rainy day, the car was really responding poorly to acceleration at all speeds. I was able to drive around, but I couldn't count on the car responding right away when I hit the gas pedal. And the car would shudder at times. Then, I didn't drive the car for a few days, and then it was dry, no rain, and the car ran better. So I am thinking humidity makes the problem worse.
I have also noticed over the past few months, that the car runs best when I start it up after a few days of not running it. Then if I drive the car a few miles and let it sit for about 2 hours or so, it would idle weakly when I would start it up again. The car's been doing that for several months now, but it wasn't really affecting the drivability or the response of the car when I hit the gas pedal.
Now it's gotten much worse. So, I've already replaced the following items myself to no avail: mass air flow sensor, oxygen sensor, and egr valve. I am guessing the next thing to fix is the pcv valve. But I also think it might be the fuel pump. My first guess though is the pcv valve. What else could it be? And is there any easy way to test to see if the fuel pump is going bad? Or should I just take out the pcv valve and see if it looks bad?
Buick - Regal :: Rough Idle / Misfire On Cold Start - Leaking Fuel Injector(s)
1991 Buick Regal, 3800 V6
Having a rough idle on a cold start. After some research and closer inspection of the vehicle, I'm quite certain I have at least one leaking injector that is flooding a cylinder and causing the car to misfire on a cold start. I'm also not at the gas mileage I should be at.
So I'm wondering, is fuel injector replacement as straightforward of a job as it looks? Any major issues I could run into in doing a replacement?
I'm planning on replacing all six injectors (I can get them for $50 each buying online with a discount code), but given that the vehicle is so old am I better off just replacing the faulty ones? I'm assuming pulling the spark plugs and seeing which cylinder is wet will tell me which I need to replace.
And one more question: Is there a way to depressurize the fuel system when I park the car for the night, thus preventing fuel (or most of it) from leaking into the engine until I get this fixed? I've read that just unscrewing the gas cap can depressurize the system.

View 11 RepliesBuick - Regal :: 2001 - Idle Right After Startup But Die Once Put It In Gear
2001 Buick Regal with approx 250,000 miles. 3.8L V6. Non supercharged It's my son's car. Used to be mine, I bought it with 19,000 on the clock.
The battery succumbed to the cold weather last Monday. On Tuesday, I put a new battery in, which itself now works fine. However, since then, the car refused to idle decently. It'll idle right after startup, but once you put it in gear, it'll die. When you start it, it seems to idle normally, you can let it warm up a bit and it'll settle down to about 900 rpm. BUT! Once you put it in gear, it'll stumble and die.
This problem started after battery replacement, so I have to wonder if it's somehow related to that. It ran fine before the battery died. I checked everything over thoroughly, and visually everything looks OK. No loose wires or hoses, etc.;
Today is the first time I've had to work on it since the new battery, so I thought I'd get it out there. I'm getting ready to go put a scan tool on it and will report back with those results.

View 1 RepliesBuick - Regal :: 2001 - RPMs Will Drop And Car Will Jerk Forward
I have an 01 Buick Regal GS, 82k miles. When I baught the car it had 80k miles but had been sitting for a while. I put in a new battery and changed the oil as soon as I got it. When accelerating the RPMs will go up but the car won't accelerate as fast. The RPMs will drop and the car will jerk forward. And then accelerate better after it is warmed up a bit. I thought to give it some time and maybe it will go away. 2k miles later it is still doing it. What it could be?? I would like to see if I can fix it myself.
View 3 RepliesBuick - Regal :: 1999 - Steam And Weird Noise After Driving Through Puddle
Tonight when I was driving home, I drove my 1999 Buick Regal through a deep puddle kinda fast- the water went up to the windows on my car. A few seconds later, when I was pulling into my parking space, my car started to make a "mrrrrrmrrr" sound and I noticed steam coming off the right side of my car where the puddle had been. I was able to park and check under the hood but there was no smoke- just some steam and a little bit of a burning rubber smell. There seemed to be some water on the engine- not a lot, it was already drying up when I took a look at it. I also noticed that there was also an oily (not all oil- just oil mixed in the the water puddles on the ground) trail from just outside the puddle to where I had parked. I let the car sit for a few minutes and then drove it a few feet to repark it. It seemed OK- it didn't make the noise again or steam. No lights came on. Is it possible that I've seriously damaged my car or could some water have come up under the hood and onto the engine causing the steam and some oily runoff?

A couple of weeks ago my 2005 Buick century start making a noise when i hit the brakes and all the lights on the dash lit up like a christmas tree. The noise it makes when i hit the brakes is like humming sound and the pedal will get kinda spungy and push in and out, if i keep driving it stops and all the lights come on (abs, trac off, service engine, and sometimes the brake light as if the parking brake is on) after all these lights come on the noises stop and the brake pedal works fine. I was told that the anti lock brake pump was going bad but I didn't realize there was a pump.
View 3 RepliesRegal :: 1995 Buick Not Cranking Over?
About the Car: It has 101,00 miles on it. I haven't own this car for long (less than a month). I bought it pretty cheap to do some grocery shopping with. I have no plans to drive it more than 10 miles in a trip. I have a bicycle with a trailer, but there are days in the winter when the weather says, "No" to bicycling. I had the fuel pump and filter replaced at a shop when it wouldn't start a couple weeks ago. They said the fuel pressure was low, and it needed to be replaced. It was fine for a little while, but then it wouldn't start for the past three days now. No cranking at all. I can turn on the radio and roll windows up and down, though. I do remember seeing a Check Engine, Battery symbol sign, and a couple other lights off-hand. I'm at work right now.. so I'll have to go home to see if the Security light also was there, too.
Also! I did find an electrical line that did not go anywhere... not sure if that has anything to do with the fact that there is no window washer fluid tank (wipers do work).
After reading a little about other Buicks in the forum not cranking, I will definitely try the Security Light issue after I get home from work.

I have a 1999 Buick Regal GS with a supercharged 3.8 liter engine and 161,000 miles. I bought the car off of my uncle and he said he would have to change plug wires every month to month and a half because it would start missing so bad. When I first drove the car it would quit on me at red lights and in parking lots, it only seemed to do it at low idle speeds. I live on a hill with a blacktop road and I had to give it a lot of gas just to pull the hill it was missing so bad. The plug wire had a lifetime warranty on them so I replaced them and it stopped quitting on me but I still had a bad miss at random but not as bad it would just be like hard jerks. I added sea foam fuel injection cleaner and had the fuel filter replaced. The mechanic checked the spark plugs and he said they were like new AC Delco. I also cleaned the MAF Sensor (the mechanic told me to and how) because the engine did not run steady at idle and it seemed to work that, but not the miss. Could my problem be the plug wires? They are carquest brand 7mm wires.

View 2 RepliesBuick - Regal :: Bumpy Ride At Various Speeds
Here over the last week or so I've noticed my car start to have a bumpy ride around 35-42 ish mph, and around 65-70 ish mph. It feels worse probably around that 40 range, and seems to be even more pronounced during acceleration. It's not a super high frequency or anything, maybe just a couple hundred HZ. I have been driving it considerably more over the last month with my new job (around 140 miles a day, mostly highway/interstate driving). I've got an oil change/ fluids checked about 3 weeks ago or so.
