Today me and my son installed a new K&N air intake on his 98' passat 1.8t, everything looks good but when you start it up the engine does not idle properly and it now starting to smoke.. Also it is leaking some sort of black gunk out of the exhaust pipe, we didn't drive it but when you give it some gas it hardly accelerates.
View 4 RepliesIt levels off and idles fine after about 10-15 seconds but sometimes it idles so rough I think it's going to stall.
View 14 RepliesI have a 1.8t jetta that has a weird idle issue when starting and engine is cold it like to idle at 1200 rpm then will eventually work its way down to 800 rpm
I have no cel codes and have looked for vacuum leaks (but may have missed one) ,but if i start the car and it idles at 1200 rpm then i shut it down and start it right after it will idle at 800 rpm as normal.
Its a 1.8t unitronic stage 1 stock everything except e type coils with plugs at .032, Also does not have much pull after 4000 rpm, not to worried but just may be part of the issue....
I'm needing cold engine misfire. 2001 escape 3.0 engine 190300 miles on it. I changed the plugs, cleaned the fuel injectors, new air filter, new fuel filter, cleaned the pcv valve and new ideal control valve. When the engine is cold it starts right up but wont idle right and misfires sputters some to but run the rpm's up and it smooths out. drop to idle and it misses. Now when the engine gets to operating temp it seems to run fine. What am I overlooking to find the problem?
View 5 RepliesI have a 2000 f150 lariat 5.4L 4x4 and when i start my truck up when it is usually below 40 my truck will idle around 300rpm and shake. It also makes popping noises in the exhaust. I am getting codes PO171 and 174 (running too lean in both banks) I have replaced my IAC, plugs, pcv valve, air temp sensor and MAF sensor and 02 sensors and nothing has changed. I have tried looking for for vacuum leaks using carb cleaner and starting fluid but i nothing has came up. I took it in to a mechanic and he suggested a bad intake manifold but i searched for a leak and found nothing.
View 14 RepliesI'm new to this whole working on my car thing and I would like to add some stuff to my car. Is it even possible to get a cold air intake on a 2006 VW Passat 2.0T ? If so i cant find one anywhere.
View 10 RepliesWhenever i leave work, i have to go in reverse to exit the parking lot. I noticed that the brakes are really ....mmm.....I am reversing and I press the brake to the bottom (it bottoms out very quick, not full lenght) and with it pressed at max the car barely stops. I almost hit the car that was parked on the other side..I freaked out cause I was at the bottom with the pedal and the car wasnt really stoping, so I pumped it up and it got harder and went lower to the bottom and it actually stoped and got responsive. I didnt notice that while going ahead from home, going forward. No issues whatsoever in normal driving. Pads are ok. Noticed that it is getting worse on hot days. Now I pump it up a few times before I even take out from park.
View 2 RepliesMy 2001 Buick Lasebre is not starting properly. I have to pump the gas several times before it will start; then when it is started at low speeds or idle it wants to stall. As long as I can some how keep pushing the gas peddle it wont stall. On the other hand when I am driving at higher speeds, anything above 40 or so it runs perfect. The check engine light was on and shows EGR valve stuck open. I have replaced the Mass airflow sensor, fuel filter, and the EGR valve. I had the code cleared and a short while later my check engine light came back on with the exact same reading. I bought this car only a week ago and was not expecting to have to fix a car I just bought and ran fine while test driving it. I have read may different forum that say that it could be anything from my fuel pump to vacuum hoses, to some other sensor.
View 19 RepliesI just purchased a 98 Passat 1.8t with 100k and noticed when I let it warm up for more than 10 minutes I start to get white smoke from the tailpipe and the ground underneath the pipe is wet. I can't figure out if its a head gasket because my coolant hasn't gone down too much or if its a problem with the turbo.
View 2 RepliesI installed an Injen cold air intake and 2 days later, the check engine light went on. I had it reset at the dealer and next day, again. Am I stuck with this or is there a way to keep it off, other than putting back the original air box?
View 18 RepliesI have taken my car into service twice because of the check engine light being on. They fix it and say it has something to do with the intake. It is now on for a third time. Obviously they are not fixing the problem. BTW, I have done no modifications to my car.
View 7 RepliesI've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.
View 1 Replies2004 Passat 1.8t that is intermittently not starting. The problem only happens when the car is cold. When I turn the key, the car cranks just fine but will not start. All of the dash lights light up and I had the battery tested and it is fine. Tonight it took about 5 minutes of repeated cranking and waiting before the car started.
After a 15-minute trip home and it had a chance to warm up, the car starts just fine. I've taken it to my mechanic but they haven't been able to replicate the problem. I'm thinking about leaving it overnight just so they'll be able to replicate it.
Not sure if it could be related, but I just had a coil replaced a few weeks ago (the coil was <1 year old). The plugs are only 3 months old.
Got a check engine light, whoever scanned it said something about a secondary air intake? Upon searching, I found a post about a bad MAF.
View 2 Replies1.8 turbo 99 passat that is smoking a thick white smoke, doesn't smell like oil, doesn't smell like coolant, not gas either. Compression checked good, no bubbles in the coolant, no coolant in the oil. It only does it when you let it idle for a while but when you drive it the smoke goes away, clears out so to speak. Its an automatic,wagon if that makes a difference.
View 4 RepliesI own a 94 Toyota Pickup with 265000 on it. And I have a question. It blows white smoke but ONLY when the engine is cold. Is this something major? Or can I ignore it?
View 2 Replies1. 1 month before I change my car battery.
2. Last night, after coming from Office i.e., around 50 KM drive. I witched off the car and had my dinner, let say after a gap of at least 3 hrs, I try to restart my car again but I could not. Even I can notice that the battery is not discharged as all lights are functioning properly & even center lock is working fine.
3. Then I use another car for jump start then the immediate car started. After driving for another 25 km, I switched off the car & try to restart again but I failed.
4. Today, after a gap of almost 15 hrs, again I tried to start the car then immediately it got started without showing any difficulties.
5. Again after driving around 20 km, again I switched off the car & try to restart then its not restarting.
I am confused, what could be the problem. Sometimes, it starting when the engine is cold & sometimes it's not starting when the engine is hot.
When I turn off the car I can smell some paraffin-like fume and sometimes also even see a white-blue smoke coming from under the engine. This only happens now when the outer temperatures have fallen here to Zero Celsius. I didn't see anything similar earlier when it was warmer!
I also can hear some weird buzzing sound for about 2 minutes coming from the areas of the left and right front wheels. I've put on winter tires yesterday and found nothing wrong there in wheels area. I am thinking about a fuel pump/pipe or perhaps something with AC/heating, or oil burning... Or is that OK?
Or is this something releated to the diesel particulate filter? I was driving just some short city distances last days....
Where exactly is located the particulate filter?
So I have a weird situation. My Sonata GS with the 2.4 engine has trouble starting ONLY during cold weather (-2 or colder) if it's been sitting for a few hours. If the weather is warm, then it starts fine most of the time. The car tries to 'fire' for about 45 seconds before it does; and 'fires' with no hesitation at that point. The car runs fine, no hesitation or rough idle. I've cleaned the intake system to make sure it's not clogged or dirty, replaced the air filter, cleaned the MAP and throttle body. My battery died a few weeks ago, so I've even replaced that. What this could be? Everything I've researched or looked into would throw a code, or have symptoms while driving...yet it runs fine once it's started, and no codes/lights are showing. Don't want to just start swapping parts hoping to find the problem...
View 14 RepliesI have a 2000 Accent with 90k miles. The last week or two, it takes about 5- 6 seconds of cranking to start when the engine is cold. Having had the car since new, I know that it's not normal.
The engine seems to crank strongly, and once started idles and drives well. This occurs once about every 4 starts when engine cold. Warm engine starts normal.
Changed plugs - no difference. Maintenance current per owners manual schedule.
Went on a road trip over the weekend and had some problems with the A/C. 200 miles into the trip I noticed the fan with the setting on 4 started to get weak and wasn't very cold. After getting stopped for a speeding ticket and sitting idle for 15 minutes, ice chunks starting flying out of the vents. After this happened it was fine.
