eqvance Posted October 26, 2006 Share Posted October 26, 2006 i know this is a subaru forum. besides my subaru, i've got a 1997 jetta 2.0 gas. it stumbles upon acceleration. i havent gotten much help from jetta forum. car smooths out as long as rpms are up. runs good when cold. also when adding gumout fuel injection the problem gets better. airflow meter or problem in throttle body? this forum has been great for my subaru. can anyone help with my jetta thanks Quote Link to comment Share on other sites More sharing options...

porcupine73 Posted October 26, 2006 Share Posted October 26, 2006 A coworker recently had a similar problem with his VW I think it was a jetta, we read a code of the CEL but I remember what it was, something like bank #1 long term fuel trim issue; I think he had the MAF replaced and that fixed the problem.

eqvance Posted October 27, 2006 Author Share Posted October 27, 2006 thanks for getting back with me. i hope it is the air mass rather than throttle body. i will take it to dealership and put on diagnostic machine. their is no check engine light on though. they will charge me about 120 bucks. i dont know much about throttle bodies, but they told me a new one would cost 600 bucks. its got to be some sensor, since its worse as the car engine heats up. also strange the the problem clears up with fuel injection additive. thanks for your time.

Virrdog Posted October 27, 2006 Share Posted October 27, 2006 What Jetta forum? Here? http://forums.vwvortex.com/zeroforum?id=3 That's where I would go if you are not sure. Do lots of searching specifically in the MK3 Jetta forum. Quote Link to comment Share on other sites More sharing options...
