Q45 sputtering when it gets warm

My q45 sputters when the engine finally warms up. It will drop in rpms but if i keep my foot into it, it'll bounce back. then drop off again and back up. If im coming to a stop it occasionally will stall. If it stalls, it starts right back up no problem, once i had to put my foot into it to keep it from stalling again on startup. but then will go back to running normally again like nothing happened. But ive noticed it only acts up when the engine finally gets warm, has its little hiccups and then drives normal again. PLease help

SOURCE: will sometimes stall at stops, feels like its

First of all you need to access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the ECM.
Let me know please about found DTC's. I will assist you kindly to fix the problem.

1992 Chevy S10 2.5L-4 cylinder. just started today outta no were. it idles really rough and pops then when i step on the gas it sputters and pops also smokes a little. help please..


My 1990 S10 pick-up had a similar problem too. It would start up fine (while the engine was cold) then once the engine warmed up it would idle very rough, sputter, and even stall out. My grandpa and I found what was wrong finally. The fuel distributor had been cracked, so when the engine warmed up it would miss (giving either too much or not enough fuel). So I recommend that you check that. Hope this helps.

When engine gets hot it spits and sputters


I would change the thermostat, if the engine is cold, the computer will send more gas ( Like a choke in the old days ) after warm up,, the car sputters,, you could also have a clogged fuel filter,

5.3 chevy hesitates when cold runs fine after warming up


what is the fuel pressure reading, sounds like low fuel pressure, you should have 60 PSI at idle and more when you throttle the engine up about 65 PSI, it should NEVER go down.

Sputtering Engine


This is normal. Four cylinder engines do not have a lot of horsepower and torque.

When your a/c compressor and cooling fan kick on, there is a load on your engine that casues rpm to drop. When it kicks off, the load goes away and the rpms go back up.

Your a/c system is the cycling type that increases fuel economy. It should cycle 4 to 7 times/minute at 70 degrees F.

Please rae as fixed if this answers your question.

PS. With the a/c (and defrost) off, it should not drop any rpms.

When the temp is cold 40 or below my grand prix won't stay running, its like the carborator is over loading. I can be driving and have to let of the accelarator and it will just die. If I try to warm it...


I'd concentrate my time & money,( $15.00 ) on ECT, "engine coolant temperature sensor" If your V6, is a 3.8, and not a 3.1 then it should be located (threaded in ) right below your throttle body at intake/block area. My guess is the sensor is telling the ECM that engine is already warm, thus only delivering enough fuel for a warmed up engine. Once engine is warm, all's well.

1996 ford taurus is losing power and rpms when engine gets warm


If it was a dealer, go back & have him scan it for fault codes. Usually cheaper to have it scanned and replace one faulty part, than replace 5 parts before you hit the right one. Autozone & PEP boys apparently will scan for free if you bought it private.
