Car won't really accelerate past 30
04 Buick le sabre. Couple days ago it turned off on
the freeway, the word volt popped up on the dash.
Pulled to the side of the road. Started back up but it
started to shake and drive rough. It still accelerated
past 30. Still went past 90-100.however during
acceleration the check engine light blinks when it
goes past 30. Autozone tells me it needs a tune up.
Couple days later , I get the full tune up, plugs,
wires , and filter. Guy fixing finds out one of the coils
is working. We go get another coil. And it still isn't
working. So I suggested if it was the ignition control
module. And he says it could be. But I don't have
the money for it til next payday. Could this be the
problem to why I'm not getting over 30. Oh and btw
it goes over 40-50 and so on eventually. But it only
does this when I let off the gas and tap on it lightly
then let off of it and start tapping on the gas again.
So back and forth doing that gets it over 50. But I
can't do something like that getting on to the
freeway. Helppp please
you need a real mechanic , if you try and go cheap it's just going to cost you more
He is a real mechanic
then your problems are solved
Scan for the codes again and post it back here. Sounds like a misfire. If you have this for a period of time it could have caused or will cause other issues. Unburnt fuel into the exhaust can clog up a catalytic convertor real quick. Chevy is right, find a mechanic with the right equipment and diagnostic tools that can pinpoint your issue instead of guessing and swapping parts.
You took it to Autozone? Do you really want people making just above minimum wage offering advice or repairing your vehicle?
