Question about 1991 Lexus LS 400
Hi guys, just brought my ls 400 with a running problem. the car starts fine and come off cold start. after a couple of mins it coughs and cuts out. Much like its running out of fuel, it then starts but almost instantly dies.Previous to this the car was cutting out sometimes after 100 miles! other times after only 10. It seems to have become more frequent.
Help would be much appriciated, Ed.
I have the exact same car that had the exact same problem. I looked high and low for months trying to figure out the problem. I changed the fuel pump, coil packs, spark plug wires, plugs, throtle position sensor and nothing fixed it. It would crank fine, but when it warmed up it would spit and sputter like it was running out of gas. It would shut off and would not crank back until it cooled off. The computers in those cars have something wrong with them causing it to starve the car for fuel. I sent my computer to Auto Computer Exchange in Davie Fl. They repogramed the computer with a one year warenty for $305. I put it in the car and It is fixed. One other thing that might happen with this car is the insturment cluster will go out. These cars are known for that. If this happens just go on Ebay and buy a rebuilt one for less than $100 it wil have a lifetime gurantee. good luck Ed
