1999 saab 9 3 loss of power going up hill and when accelerating, have had the catalytic converter replaced, the turbo thingy checked and blown out, the muffler checked and found no problem, It has been put on the machine at 2 different dealers and no problem found...
View 1 RepliesTowing a 5th wheel at about 10,000 lbs total. Towards the end of out 9 hour trip home and going upgrade the truck begins to loos power and the engine starts making some bad sounds. Although its hard to hear it starts about 45 seconds in and continues later when going uphill. the truck also made a very high pitched squealing/scraping sound (not a belt) like it may have been coming from the turbo. Oil temp was about 220, trans temp at 170 at the time of the event.
Truck has 216k, stock, upgraded trans cooler, original fuel pump.

I bought 08 6.4 113000 on it 4x4 lariet drove 300 miles home. No problem 2 days later runs fine for 45 minutes than loses power and sputters up hills starts no problem every morning every time wait awhile sometimes runs fine was on e when test drove canged both fuel filters oil and drained 8 quarts tranny fluid and replaced it. When problematic rpms wont go over 2 turbo psi seems high seems in sync with rpms dropped...
View 3 RepliesI have a 2006 Saab 97x. While the car is not very common, the GM 5.3L V8 in it, is. It runs perfectly fine under normal driving conditions but for the past several months it has been running like a Slaab instead of a Saab. It has been backfiring, sputtering and has had loss of power issues but only during hard acceleration.When my check engine light came on at 50k, the dealership changed all 8 iridium plugs and when it happened again at 75k, only one was replaced. Aren't these supposed to be 100k plugs? One of the exhaust manifolds has been replaced due to a leak and the other one has a leak now. Fortunately, all of the previous repairs have been covered by my warranty. Unfortunately, my warranty has run out and the other manifold is no longer covered and seemingly neither is this problem. Most recently, my new mechanic used some fuel injector cleaner something or other to no avail. I tow a 5000# camper and can't have these issues when summer comes. Is it the plugs, manifold, engine, something else?
View 1 RepliesMy issue can be while driving with cruise on, or accelerating, the truck just losses power, then recovers. At idle, the rpm can, but not always, fluctuate.
There is no "misfire" when it happens, but it just falls on its face. I have NO diagnostic tools, and my injectors are not stock, so I am unable to unplug my DP.
My thoughts are to unplug the ICP and give that a shot? Meanwhile, I will put in a order for a elm327
SAAB 2007 9-3 - Recently my car has been having a rough idle and stalling on start up. It has been getting worse and I need it fixed ASAP for a long trip coming up. I cannot have this thing die on me while I'm 300 miles from home....
At stop lights the car will have a rough idle while in park and reverse. While in neutral, nothing. As soon as I accelerate, it goes away but does have a lack of power if I really push the pedal. Once I am in 3rd/4th gear, the car feels normal with no issues. If I am on the highway and slow down then need to accelerate, it goes back to losing power BUT if I change over to manual and downshift, car gains power and goes back to normal.
Here's what I have done so far:
1. Changed the spark plugs twice. Once with cheap ones, the second time with expensive ones. I also swapped out the boots.
2. Cleaned the MAP sensor
3. Cleaned intake sensor
4. Replaced air filter
5. Changed oil
6 New battery
The engines gives no codes whatsoever and I have taken it to a couple places and their readers don't see any codes. My SAAB has a built in fuel filter and this cannot be replaced unless you replaced the whole pump (to my understanding). I plan on buying some Seafoam today and see if that works. Also, I have been told to clean my air intake valve but I cannot get the damn tube off! I feel that if I yank and pull on it, it's going to damage the tube. I am not seeing any obvious leaks anywhere. One thing that is weird about my car, since I have bought it used a few years ago, my headlights/tail lights/blinkers go bad QUICKLY!
I lose power in my 97 Plymouth Breeze when driving up hills. Drives fine everywhere else but I lose power going uphill. Replaced the plugs and wires.
View 2 RepliesMy 1999 GMC Suburban just started "catching" when accelerating uphill and going 50+ mph. Does not occur any other time.
View 4 RepliesI just recently bought an 06 Santa Fe with a 2.7l v6. It was a rebuild. It had been hit in the left wheel. The lot put a new fender, suspension parts, axle, etc. It only has 25k actual miles.
We took it on a 100 mile trip today. I noticed if I am going up hill and it has to downshift, it feels like it looses power. The car continues to slow... Like the tranny is slipping. I stopped at Walmart and found the tranny fluid wouldn't even register on the dipstick. I bought Valvoline max life tranny fluid that matches the sp3 specs in the manual. I had to add almost 3 quarts before it was full. I think they may have forgot to add fluid back to replace what leaked out after they replaced the axle It didn't seem to work though when I continued to drive. After I stopped and let it cool about 30 minutes, it did seem a little better.
I guess my question is should I replace the tranny fluid? If so, what should I replace it with? Is there anything else what could be causing this now?
Occasionally my 2013 tdi has weird transmission issues. Usually it is from a start from a stop sign, typically when I am driving uphill. What happens is I step on the gas and it takes maybe 3-5 full seconds to respond and actually start moving. It is a total loss of power. What could be happening? I took it to the dealer and they said they "tuned the transmission" or something that I don't really buy because I still have the issue occasionally. I had this issue from day one and now have about 25k miles on the car.
View 6 RepliesIt's a 2006 Ford F250 6.0 diesel with 307,000 miles on it. Up until a week ago it ran great but when I was in a drive thru I turned it off (to order) then turned it back on to pull up but the idle was very rough and the truck shook as I revved it up but it went back to normal after I saw a puff of white smoke. Ever since then every few stop lights I will begin to accelerate but there isn't any power and it shoots out a lot and I mean a lot of black smoke for a second then the turbo spools and it's normal.
Today though I turned a corner and began to accelerate after but I had no power at all it shot out an un manageable amount of black smoke mixed with very little white as I pressed the pedal. I put the pedal to the floor and the rpm were up to 2000 still no power I out it in tow hail still pedal to floor and now power! At this point I pulled over and called my dad figuring the truck wouldn't move anymore but I got no answer so I tried to go again seeing how ideas almost and and the truck worked fine small amount of lag but it ran made boost and worked until I got home. What could it be? I've heard maybe my turbo is bad maybe my egr valve but I'm just not sure.
2001 Hyundai Elantra GLS ... I don't know what is going on with my car. When I start it, put it in gear and try to pull out, it feels like there is a loss of power. A few seconds later, the power returns . I can push my foot down, and the engine doesn't rev, but then it's like all of a sudden the engine realizes I have my foot down and takes off.
View 3 RepliesMine is 2006 with 130k miles. Just replaced fuel filter, air filter, cleaned air flow sensor and cleaned the injectors. The car still feels slow and it seems to eat more fuel than before. The spark plugs and the wires seems to be ok. No warning or error on dash is displayed.
When push the accelerator it takes a while to respond starting from stop position, and when the car is moving and try go faster it feels like lazy so I have remove the feet of the pedal and push it again so it respond quickly.
Air blowing noise that sounds like a disconnected turbo or hose. Loss of power accelerating and downshifting.
View 4 RepliesMy 2.4L 03 XLE with 220k on it is losing power. Running fine other than not accelerating or going up hills as well as it was last week. I have P420 cat code for the past 40K. It also has the typical smoky start from leaking valve seals and uses about a quart every 1k miles.
Ran a can of 44k through it and I'm about to pull the plugs and see what shape they are in, but I'm wondering if this loss of power might be the cat. I've been searching and it seems a plugged cat is a common cause for power loss. Seems likely since I use so much oil.
Seen the DIY replacement and leaky seals Rockauto suggested replacement Eastern ECOIII as well as the Walker.
'01 Silverado with the 4.8, sitting at 160k right now. I'm starting to notice a loss of power in the truck, when pulling out and accelerating it doesn't put you back in the seat like it used to and when going up a hill you have to force a downshift to not lose 15-20mph... it just seems like I'm pulling an invisible trailer back there. The fuel pump is about 1 year old, fuel filter less than 3 months, plugs and wires are about a year and a half old, PCV valve about 6 months old, fuel pressure regulator about a year old..
View 3 RepliesMy wife has had her 2010 3.5 Santa Fe since new. Over the past year it's been having a clunk develop when accelerating, happening a few times from a start until highway speed. The clunks almost feel as if one is driving over bumps - that's what I thought at first. The power doesn't seem to be there anymore either. I have been driving her vehicle the past three years and it was fine when I first started driving it. But the past couple years I first noticed a problem and it seems it is getting progressively worse. My wife now notices it quite a bit too.
View 1 RepliesIt did this funny thing about 4-5 times over a span of about 24 hrs before dying and then won't start. It was like hitting the limit on a speed governed car.....sudden momentary loss of power..and it seemed to be when accelerating if that matters. The thing I'm sure of at this point is that the fuel pump is not coming on when the key is turned, I know that sound well, but also checked it at the external connector with a test light for thoroughness. I also found a blown fuse under the hood which coincided with a little smokey smell inside the car when the fuse was replaced and blew again.
There is no spark as well. My Haynes book says that the PCM is behind the passenger kick panel but I only see the eecv and it doesn't smell burnt. The IFS is good. There is power at the coil packs. Fuel pump relay fuse is good. Is it more likely the ccrm since it contains the fuel pump relay and PCM relay or could it still be the eecv? It feels like one part failed but is causing more than one "problem", no power to fuel pump and no spark.
1994 Grand Cherokee Laredo, 100,000 miles:
Driving out to see my BF this afternoon I noticed when I accelerated it hesitated a bit. I didn't think anything of it so I let it go. Driving home was another story. I was about 5 miles from home coming up to a red light and I started to brake, the light turned green and I hit the accelerator and I got no juice, I got across the highway and started to brake and the brakes locked up, the steering wheel locked up and then I lost all power. I got the Jeep to stop (right at the exit to a train station ) I tried to turn it back on and got no juice. I just got a new battery about 3 weeks ago. I called 911 since I was stuck in the middle of the road right outside the railroad station. Officer asked me to try to crank the engine again, asked if I had gas (have 1/2 tank) and then got me pushed into a spot until I can get a tow to my house in the morning.
The car has been fine, I never put "off" gas in, try not to let the gas get below half a tank.
I have a 1997 Saab 9000 CSE Turbo. It has been a great car overall. Last summer, our water pump died while cruising on the highway, leading to a major overheat, leading to warped head. We decided to roll the dice on a rebuild, which was done by a reputable import specialty shop that has worked on many Saab 9000s. Since we got the car back 5000 miles ago, we have lost a few miles per gallon, and we hear a rough noise in the engine (particularly when it's cold). In the last few thousand miles, we lost a lot of coolant, apparently because the new water pump is faulty (the shop looked at it and agreed to replace under warranty). In the last 1000 miles (but no evidence of it previously), we have begun losing oil like crazy and occasionally (but not most of the time) smelling burning oil (the heater is on, moving air around). We are now adding about a quart per 200 miles. When we inspect the block, there is some small evidence of oil leakage, but not a lot, and there are never drips on the driveway.
Where is all that oil going? I showed it to the shop, we put it on the lift, and there is no spray on the underside, leaking oil pan, etc. I suspect the new head gasket is leaking, but there is little enough residue on the block that it's hard to be certain. What other explanations are there, and is it fair for me to blame the repair shop and insist that they redo the head gasket? The shop is a 6hr drive from my house, so I can't just drop by to discuss it with them.
When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?
