93 loyale lack of power and hesitation


Recommended Posts

Just dumped 800 dollars into my loyale to get my oil leaks and seals replaced and now it has a lack of power. No rough idle just a lack of power and hesitation when giving it gas. Almost cuts out and when i let off the gas its fine. Mostly does this when floored. Was wondering what the most common problems are? New plugs and wires? Distributor cap? Fuel pump and filter etc. Let me know your thoughts before i drive it off a cliff.

If pressing the accelerator causes power problems then it could be a fuel delivery problem.  Check the fuel filter and the fuel pump pressure.

 

Another possibility is a clogged exhaust system.  Rap on the catalytic converter.  If you hear stuff rattling inside, it's done.

Timing could be off, plug wires loose or not replaced in correct order.. did you do the seals yourself? If not the mechanic could have not understood the technique us Subaru owners know about replacing the timing belts when they reinstalled them.

I think sometimes there's corrosion between the cap and rotor, you could try a scotchbrite pad and some contact cleaner and see if it helps things.  Just make sure you don't mix up which wire goes where.  If it helps, a new cap and rotor are pretty cheap, I got the Beck/Arnley ones and they were made in Japan.  I think the NGK (9350) FE27 wires are the correct ones for these cars.

Also, if the problem only started right after the work they did, wouldn't it be reasonable to ask them to give it a once-over?

Replaced the cap and rotor and still the same problem. It doensnt show on the tach and missing but its just so sluggish. I know these arent fast cars but it is alot more sluggish then it was before. I almost want to say it it distributor timing like its off but i dont know. I would take it back today but sadley its thanksgiving and they are closed for the next couple of days
