Question about Volkswagen Jetta

2 Answers

My vw 1996 JETTA 2.0 likes to stall sometimes when idling with the clutch fully pressed in. It happens only sometimes, like when turning or on a downhill slop coming up to a stop. I recently replaced a the distributor cap and a couple wires that i found out were burnt out ( i was running on 3 cylinders for a while) and i seem to have full power now, but now this new issue has come up. It idles about 800 rpm, but sometimes it suddenly drops below this and the engine struggles or stalls to get it back up. Is there a way to adjust the idle to its higher? im not sure what to adjust, but im thinking i can try this to keep the idle a bit higher and not allow it to drop to low. any suggestions?

I had the same problem on my jetta. It ended up being a really dirty throttle body. I took my intake tube off and used a lot of carb/throttle body cleaner. Hope this helps you

Remove the Spark plugs, and check their condition, especially on the cylinder that was dead.
Replce all plugs, even if only 1 or 2 are junk.
Run the vehicle to see if this has improved the situation. Should this not cure the problem, come back with the initial result, and be as specific as you can, about what is still wrong.
Regards, DT

My 2003 vw jetta ac clutch wont engage. you can hear the car idle up as if the ac has engaged but then within in 2 seconds its stops at this time when it idles up i get a 12v signal at the compressor


IS THE SYSTEM FULL OF FREON? IF ITS LOW THE A/C CLUTCH WILL NOT ENGAGE. ITS KIND OF LIKE A FAIL-SAFE FOR THE SYSTEM. IF THE FREON IS FULL AND YOU HAVE 12V TO THE COMPRESSOR I WOULD CHECK OUT THE CYCLING SWITCH ALSO.

Start by checking the switch above the clutch pedal ... I have seen where they come loose, brake or move and when you push in the clutch it doesn't engage the safety switch all the way.

Check your vacuum lines, make sure there is no leaks, and go from there, then all you electrical connection in the engine compartment.
I have a 1996 Jetta Trek Edition, the hoses, and wire harness, are so brittle, any movement can cause hoses and wire insulation to crack.

IAC valve may be sticky or carboned up. Use throttle body cleaner to clean it up, and it should be good.

Sometimes cant idle


i will recomend you to clean the carburetor with carburetor cleaner, just buy some at auto parts remove the hose on top on carburetor and keep the rpm arrownd 2500 and keep ading the cleaner to the inside of carburetor, if you add too much it might backfire just keep you face away from the carburetor good luck and let me know
