VW Cabriolet RPM decreases


Hi, it sounds like you have dirt, water ,gunk & grime in your inline factory fuel filter ,.Its located between the tank & the inlet manifold,.
once you located, have it changed it, or have it changed, (its a steel canister with flow arrow) ,check for lacquer peel, which is a sealant they sometimes use in fuel tanks, check contents of old canister by pouring remainder into a container and check for this, it will be flacky particals, if severe, have tank tanken out of car & cleaned, this is due to not having the tank full most the time, Also, check your air cleaner , it will help with the cars performance. hope this helps, Kipper 25257603-fhf2ppg4i12i45qd5vaymkeg-2-0.jpgmake sure arrow on filter face front of car....

VW Cabriolet RPM decreases


Hello,
to me its sounds as though you have dirt ,gunk & grime ,water, in the main inline factory fuel filter, ,it will be a steel canister type, between the feul tank and the intake manifold, change filter,( u may need a mechanic, or someone handy with a spanner, once off, tip contents into and look for laquer peel, some tanks are seal with this, and it will some times peel ( especially if tank not kept full). if that is the case, have your tank taken out & cleaned, also, check airfilter, car will run better n cheaper to run, Hope this Helps.

Volvo v40 2000nx reg 1.8 NON gdi engine constant high rpm can having no thermostat cause constant high rpm or can a briken lambda sensor cause high rpm cleaned all throttle body cleaned idle valve checked...


Yes, having no thermostat can cause the car to run fast as it will still be set in it's "warm up" mode and will be injecting a richer mixture of fuel/air into the cylinders. There may be an additional cold start injector that just works while the engine is cold. You will probably use more fuel like this. It's not a great idea to run with no thermostat anyway because you get uneven hot and cold spots around the engine which is bad for it. Cheers

Hi, I have a 2006 Altima with 31,500 miles. Recently, the engine start shaking when car is Idle but I still feel the shake when driving or at red lights. My second problem is a weird loud (humming) noise...


You don't need to change the spark plugs since it has only 31.5 K. The plugs should last 60K. There is a an adjustment at the gas cable end at engine to increase the idle a little bit. You can increase rpm at idle to 600 RPM. Since your RPM at idle is low that why it is shaking at idle, red lights. Let me know it it is shaking at high speed ( 2500 RPM)

1992 VW Cabriolet stalls out


Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

1992 cabriolet will not idle


The ISV (Idle Stablizer Valve) could be clogged or just not working. It's a cylinder with 2 vacuum lines and electrical connector going to it. Just above the valve cover and below the intake manifold. Best check for that is turn the key on engine off and the ISV should buzz. If it is buzzing remove it and clean it with some throttle body cleaner or brake clean. Reinstall and check for idle concerns. Have to be quick to see if it buzzes though. Better to have someone turn the key for ya while you check the valve. If it doesnt buzz replace it. Also check the switched on the throttle body. See if any of the wires are broken.

I have a 1992 VW Cabriolet about 3 000 rpm it


The vibration at that high rpm is most likely coming from the torque convertor and if a manual transmission , then clutch issues.
