Passat (B5) :: 1.8t Occasionally Loses Power
Jan 31, 2012
Every once in a while, my B5.5 1.8t will lose it's power. It has a Gonzo Stage 2 reflash on it, and a 3" cat back, everything else is stock. Right before I put the exhaust on, I went to go for a rip, and the car lost boost and the DV fluttered. I put another (used) DV on it from a 1.8t A4 the day I put my exhaust on, and the car ran better. Last week I was in a hurry, floored my car, and it seemed to have went into limp mode or leaked boost.
I could hear the turbo start to spool, and then it stopped at like 2500-3k. I parked the car when I got home, and the car was fine until yesterday, where it did the same thing again, with the same exact story. Today my car ran fine, and has decided to keep losing all day. I just ordered my boost gauge tonight, and plan to get a Forge DV, but idk what it could be. MAF?

I have a 2002 Nissan Frontier that a had a buddy perform a tune up. Now my buddy has disappeared and my truck miss fires on start up and occasionally looses power when you drive it. I also noticed that It consumes more gas. I went from 305 miles on a 17 gallon tank to 230 miles.

I have a 2006 Ford Escape that's turning into a mystery. Over the last few months the warning lights have been reporting issues with the overdrive. I've taken it to the mechanic who hasn't been able to identify the issue.
He's cleared the issues from the ECU, and the car doesn't complain for about 2 weeks, then it reports a different issue related to the overdrive (eg: OD or transmission).
Possibly related, the car occasionally loses power on acceleration. When taking off from a stop, it'll be really underpowered while getting up to speed. This only happens occasionally.
Is it a part failure, or could it be electrical or related to the sensors?

This happened twice this month and each time was after driving and then turning car off to go into a restaurant to grab food real quick. Start car up back out, put car in drive and before getting out of lot loss of power followed by car stalling and only battery indicator comes on. Car starts right back up and seems to run fine. No CEL.....? I'm assuming I cannot scan car if no cel is on. I was thinking cam position sensor or fuel pump. I'm about ~1100 mi over for oil change which I am getting Monday.

So the 04 is rolling down the road when the cluster gauges ping, the truck loses power/acceleration but the radio never goes out. Have a new alternator and batteries passed a check. It has done it three times. We are 1100 miles from home. OBD and cigarette lighter fuse was blown as well.

I have a 1999 Ford F450 Tow truck with a 7.3 turbo. It loses power and misses when I give it gas but when driving normal speed no problems.
I had a ford technician look at problem with a computer and he said number 8 injector . Today number 8 was changed.
Test drove it same problem. I also changed th fuel filter. And I emptied the tank to make sure No water

1994 f250 7.3 turbo problem.. runs great on the level.. Cruises 65 no problem.. We have an 8% grade coming from town and half way up it starts cutting out and sounds like a jack brake under the hood and loses power.. Once over the top it clears out and runs fine again.... I just changed the fuel filters but no luck... I have been wrenching on cars all my life but no diesels..

The last couple of days with the temps in the 50's, my 2000 F550 with a 7.3, will start normally and idle fine. When I try to drive it, I get less than a quarter mile and it just looses power and will die.
If I flutter the pedal, sometimes it will keep running, very poorly. And when it does this, it is putting out blue smoke. After it does this, it will run fine. Just like nothing is wrong.
What do I look for, or is this normal. I have had the truck since last October and this is the first time it has acted like this.

I am a mechanic and tow operator running a late 99 f350 7.3 6 speed cab and chassis wrecker. This truck has had a hard life and has been neglected for quite some time, and now has become my baby/headache. Truck starts great, idles nice, and will run great for about 5 minutes until it starts billowing white smoke that smells like fuel and loses all power. If you continue to drive it it will die. Sounds like it's dropping cylinders and will barely idle. If you stop for 5 minutes or so and let it idle it will smooth back out and will run great again for another minute or two, then right back to stumbling.
Using torque app, hpop pressure looks good when it's running well. Peaks at 3k, IPR maintaining 30-40% max. As soon as it stumbles you can see the hpop drop to 5-600 and the IPR will climb to 65%. Let it idea bit and they go back to normal, and stay good until it stumbles again.
Ive changed the fuel pump, ICP,rebuilt FPR, change fuel filter, pulled and cleaned the fuel tank (metal tank, no delamination, looks perfect inside). Pickup screen looked good. Cleaned the IPR, cleaned the hpop reservoir, there was no screen inside. Checked voltage at fuel pump, 11.78 across the pump with it running. Pulled valve covers, no noticeable leaks around injectors. Injectors have less than 5k miles. Remans with 100% larger tips.
To me it seems like the lpop is not keeping up with the hpop under load, starving it until you idle and let it catch up. Could it still be bad injector orings? Bad lpop? Something I'm not thinking of?

I've got a 2005 F350 that i recently did balljoints, tierods and shocks/stabilizer on. Just stating that because i don't believe anything could be binding up to cause this.
If i am to take a left turn, more than 45 degrees, the truck will seem to lose power assist on the return to center and be very stiff when i return it by force until i jerk the wheel past center and let it come back the other direction and it seems to regain power assist.
Also, the steering is just generally bump. I have not driven a better condition 2005 to tell the difference but i'm sure this isn't the way it's supposed to be
I am not having any issue with braking force, as of yet. The first winter i got the truck i blew a power steering line that goes from the gear to the cooler, in which direction i don't know. It's been a year and a half since then so not sure that caused any failure.
Before this symptom the pump would whine when on left turns only, no problem turning right if i feel like doing right turns the rest of my days. I guess what i'm getting at is, does this sound like a bad pump? Bad gear? Both?

My 740 GL has recently developed a strange problem. Regardless of speed, whenever I push the accelerator to near wide open throttle or WOT, the engine loses power. It idles down to about 1000 rpm and will not respond until I pull over, turn off, and restart. It doesn't exhibit this behavior when in park. The car runs great otherwise (85+ mph) as long as I don't get close to WOT. I replaced plugs, wires, rotor, cap, coil, and fuel filter.

My car loses power when it's to hot outside. When pressing the gas from a complete stop it can barely get going and then within a few seconds the power kicks in and it goes. One summer I was away for 10 days, when I came back, it started, then stalled and died. i took it in, the dealer said the main computer chip had re-scrambled it's self. this has happened twice, the dealer could not give me an answer as to why, but they were happy to take my $260 to fix it. 2006 Ford Escape Hybrid...

My 3.5 intrigue seems to stumble while driving it. It feels as it the engine is stumbling or loses power for less than a second and it will do this a few times in a row and will be fine for awhile and then repeat itself.
This can happen while cruising, slow acceleration or at a stop light. I don't really notice it under harder acceleration. When it does happen i do notice that the rpm's drop a very slight bit.

I have a 2001 ls that runs rich and shows no codes except p0300. It will miss under loads and get worse as temp rises. I can smell exhaust and burns eyes when running inside shop.

Jeep runs fine for days and then it will have a bad day. Loses power for a minute or two and then revs back up. If you stay on the gas it acts like it wants to stall something makes a loud banging noise under the jeep and then it takes off only to do the same thing in 2nd gear 3rd gear etc. Would o2 sensors try to shut it down? Throttle position sensor?

My '78 245 drives just fine around the (flat) city but when I try to take it to the mountains it seems to struggle. It makes it fine up the hills for the first 30 minutes or so but eventually it starts to chug and will lose power and die. If I give it 10 minutes to rest it will start up just fine and drive fine for a while but if I continue to go uphill it will die again. It doesn't overheat too much, it just seems like it's not getting enough of something? And it doesn't seem like it's a fuel pump because i've replaced those before and it seems different this time. After returning home from the mountains, it's like nothing happened and it drives fine?

My 2006 650i loses power under moderate to heavy acceleration. If I accelerate from anywhere over 2500rpm, it will accelerate then the engine rpm will drop suddenly by 500-1500rpm, and then will continue to accelerate again from this lower rpm. It only seems to happen once each time I punch the pedal. The car does not throw any codes. I have had the dealer and Dinan Performance examine the problem and they have not been able to isolate the problem. They have run vacuum leakage tests, fuel pressure tests, and may have checked the throttle position sensor. This really takes the fun out of driving this car. I have about 50K miles on it.

13 Elantra sedan. When I turn the key to on (engine not running) The stereo turn on normally.(NON -NAV) Start the car and it turns off, no screen, no audio, just like i hit the power button. Load up the electrical system, max A/C, headlights, Etc. It turns back on like nothing happened. Voltage on the battery is 14.3 with no load and right around 14.0 when everything is loaded and i finally get it to turn back on. Do these head units have an over voltage protection? 14.3 doesn't seem that high to me.
