Steve W. Posted June 5, 2012 Share Posted June 5, 2012 Hi Folks. Say I've been havin' problems with my 88 GL 10 Turbo car. I'm running a good wide band AFR gauge, and it's been showing a really rich state at low throttle and load,( in the low 11s) and it leans out under load and boost,(into the high 13s). So, I finally got around to testing and found the problem, the throt. switch seems to be bad. This is the late style, combo throt. switch and sensor, with the standard rect. 3 pin conn. on top for the throt switch, and a pig tail from the sensor (all in the same case) with an oval 3 pin connector. Book says it should read, .5v @ closed throt., and 5.v @ wot, mine reads, 4.8v @ closed throt., and .8 @ wot. This would seem to confirm my AFR readings. I have spare throt. switches from previous JDM swaps, but none have the pig tail for the sensor, and I've been askin' all around locally, with no success. Has anybody got one kickin' around their shop they'd be willing to sell? I'd hate to think what the dealer would be askin' for one. I've quit driving it on the highway, it's suckin' gas, and I don't want to burn it up under boost either. Hellllp. Thanks guys, S. Quote Link to comment Share on other sites More sharing options...
