Laci or Prentice, could I also beg a copy of that information, I just had a 4y-ecs truck that I had to take to the local Toyota dealer's shop since the road tech made 3 trips to our shop and could not give a quote for what it would cost to repair to get running, the dealer charged 15 hours to redo the same tune up we had done, and no further explanation of what the problem really was.
I sure could of used this information back in November 2012, thanks in advance.

It is LPG. Yes I have had that issue in the past. It was one of the first things I checked. I have seen the shielded wire with LPS units. I recieved some great Information from another person. I did notice the elec Throtle Control (carb) not responding.....running voltage tests and i think it might be seized.We will keep you posted. Thanks for the reply

Is it gas or lp? I have seen the tach signal wire **** out of the distributor going to the ecu break. I would check that. Be careful when repairing the wire because it is shielded and if grounded it doesn't work.
