Terrible fuel economy after timing belt and feels a little sluggish Options

[SiriusVirus]

So in my timing belt ordeal I was playing the throwing parts at a problem game and switched out my ignition coil and never marked the position in dizzy was at. Got the timing belt done (eventually lol) Car sounds alright sometimes a misfiring idle. I got just about 240miles on my last tank. Before this I was getting like 320-360 on a tank doing deliveries. Im at a quarter tank and I have only put 50 miles of just driving to school and work not even speeding. I replaced my spark plugs after the timing belt plugs are essentially new put them about 2 months back. What exactly is the stock degree on a dizzy and how do I get to that. (1994 celica gt 5sfe)

I think the ignition timing being off would cause the idle to either rise or fall, but it shouldnt cause a misfire. It would effect the torque at various loads and engine speeds like he is describing though.

First of all, you DO need to set the base ignition timing correctly with a timing light. Make sure to use a paperclip or piece of wire to jump the E1 and TE1 contacts within the OBD diagnostic port or the ECU will throw off your readings. On my 94 GT the proper amount of advance is 12 degrees.

Next, you should check all the components that were either removed or disturbed by the mechanic while he was changing the timing belt. If the problem didnt exist beforehand, you can be almost sure it was something the mechanic touched(whether its his fault or not its just the way repairs go on older vehicles).

Good luck and keep us updated.
