[QUOTE="jpjeep26uk, post: 438976, member: 20690"] Hi all, there is a 10 Yr old thread on this but I thought I'd start it again. My 1989 2.5l idle fluctuates between 800 and about 600 and sometimes when I take her out she does that at red lights and even stalled on me yesterday. It's noticeably worse when I turn my headlights on. Is that possible? Some kind of link between the headlights and the idle speed /rough running? I did 120 miles and she seems to run fine but that wobbly idle/ hesitation to move now and then is really annoying. Any suggestions would be greatly appreciated. (Someone mentioned running a permanent ground from the battery to the firewall? Is that safe? What gauge cable or wire should I use). The battery is fine at 13.2 withe engine switched off. Thanks all! [/QUOTE]
