2000 echo shuttering when you accelerate - 2000 Toyota ECHO

Possible fuel problems. Dirty fuel filter or injectors....this can also be an ignition problem. If any codes showing up have them checked at any Autozone for free

check for a crack in the manifold to exhaust pipe connection
to allow the engine to move ,there is normally a flexible piece of exhaust pipe in a stainless steel braid that cracks and allows exhaust sound out especially on acceleration
could be even broken at the manifold connection at the flange

Possible faulty injector low cylinder compression or intake manifold vacuum leak

Check if:-
- It is squealing or squeaking noise, the thrust bearing is at fault and need to be replaced.
- The noise varies when accelerating or decelerating, check the engine mounts and muffler Re torque all the suspension nuts and bolts. Also have a look in the engine bay area for any loose component.
- Noise is heard in any particular gear, then the transmission may require major repair.
- Check the transmission oil level.

try doing a spark test to insure that you are getting a good spark if you have a good spark then i would try doing a tune up and replacing the pcv valve and if you have a check engine light on go to a local parts house and have them do a obd2 scan and see what that comes out to be because it could also be the egr system hope this will help you out please leave a review thanks sincerely D.Jones

on the air cleaner housing

Thanks - it's on it's way to the shop.. Connie

I'd check the distributor --then the coil if so equipped --loose connection or bad ground
if ok --can you say vacuum leak or problem or EGR related
A about to fail intake manifold gasket may present in the same fashion ---pressure test it for leaks
and if it is unclear pressure test the cooling system too ---leak down test


I've had toyotas run 275,000 miles without a repair not even brake pads
on an MR2 ---had both an 85 and 87 ---actually still have them ---rail buggy project for future!
or might sell someday ---too loyal to let go entirely --rust caught up with it due to winter driving
should've driven the ole 62 international all winter --rust free all those yrs --some *(%*^ stole it out of the poconos worth 12,000 --Blue ---modified carrier from tab to flange mount --easily identified
by self even if they've swapped the vin --just need to find it ---Prosecution to the MAX
while I was away working in LAS Vegas --5 yrs ago still no leads !
HAWK --hope this helps

4.2 ltr missing. 2000 truck, f150. Changed plugs, wires. Ran great for 2 weeks. Started again. Changed coils. Got worse. Changed fuel filter, did nothing. Added injector cleaner and fuel cleaner, nothing. Checked EGR, o.k. It is getting worse. Had new gas about the time it all started.

throttle position sensor or called tps
