SOURCE: Hesitation on Acceleration or Uphill.

The knock is caused by either timing issue or a lean cylinder condition, have you checked the fuel pressure?? has the fuel filter been changed?? A bad knock sensor will not set a light unless it is open or disconnected.

SOURCE: Hesitation on takoff and on acceleration

it could be one of many things with that many miles on the vehicle. when if ever did you change the fuel pump last? both filter and pump may need to be changed. that's alot of miles remember that. the filter is under the hood on the drivers side mounted on the firewall. under the brake master cylinder. be careful to relieve the fuel pressure before changing it.

SOURCE: engine hesitating during acceleration

Ok, there are many issues here that you will need to inspect. I recommend changing the fuel filter and pump as well. this will fix the hesitation. the intake and exhaust manifold gaskets will need to be replaced as well. this will stop the backfiring.

I also recommend checking and running a teat on the PCV valve and inspect the PCV hose as well. it could have a leak or a small crack on it.

Check the air filter and change if needed. this will help with acceleration issues as well. Next, i would run a check on all plugs and the complete wire set as well. change if needed.

Inspect the injectors for leaks and lose wires. make sure they are in good condition. replace any injectors that isn't firing properly.

Ok, there are some sensors that you will need to check as well. i will list them below.

SENSOR CHECK LIST--

1. Check the O2 sensors for worn wires.
2. Check the MAFS(Mas Air Flow Sensors) Check for Damaged, Loose, or Faulty Mass Air Flow Sensor or Circuit.
3. Check the Air Cleaner Temperature Sensor. this sensor could be damaged ro have loose wires. check accordingly.
4. Check the Throttle Position Sensor. this device could be connected wrong or it may be faulty as well. replace if needed.

Be sure and inspect all the above and repair any problem spot you ruin across during your inspection.

Please rate and god bless:)

99 Lexus ES300 - Car hesitates & sputters when starting off usually until 2nd gear kicks in & sometimes when going uphill. However, no CEL. Ideas?


The flexible accordion hose that connects the MAF to the throttle body might have a small crack in it. They are sometimes hard to see, especially if in the accordion folds or underneath. Starting off or going uphill will result in enough torque to lift one side of the engine enough to open the crack and cause hesitation.

Engine hesitates going uphill


You should definitely get it scanned to read the code caused by the check engine light. That will definitely help diagnose your problem. The hesitation could be a bunch of things - plugs, air filter... They don't cause CEL's though. A turbo problem could though. Most auto parts stores will read codes for free...
