Question about 1992 Buick LeSabre
My 92 lesabre died for no reason spark was good shot some starting fluid in it ran fine so replaced the fuel filter ran great for 10 miles then died again got it home and it shows a code 21 tps could this be the problem or do you think it is deeper.........
Hi,trottle position sensor ( tps )is a very accurate diagnostic,if this dosnt fix it run a fuel presure test for a posible defective fuel pump,. good luck......
