    not sure of the one answer but we put injector cleaner in and premium gas as well the sensor etc was cleaned with throttle body cleaner and it was found that one of the plug wires was loosened when i had the lube and oil job done . although it is not totally smooth yet it seems to be heading that way. thanks so much for your help. pat

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.

My f-250 99 v 10th sputters when I accelerate sometimes stalls why?


it could be just about anything. first start by checking plugs, wires, and coil.Engine hesitation, which is normally most apparent during acceleration, is a condition that often results from either abnormal fuel flow to an engine or abnormal electrical conduction to a vehicle's spark plugs. Bad spark plug wires, whether they degrade internally or develop cracks and breaks in their outer coverings that cause electrical interference, can cause an engine to hesitate. Engine Surging, Engine surging is a common symptom of bad spark plug wires, especially if the wires have cracks or breaks in their outside insulation, heres the symtoms for a bad fuel filter. Engine Hesitation, Engine Stalling, Rough Engine Idle, Reduced Engine Power. if really plugged it will stop fuel flow and car will not start. just give it a good tuneup, and go from there! good-day!

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...

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.
