Question about 2002 Chevrolet TrailBlazer

2 Answers

SEEMS LIKE CAR IS SLUGGISH AND LOOSING POWER WHEN TEMP IS HOT.

REPLACED AIR FILTER, OIL CHANGED, 93 OCTANE GAS, BUT SOMETIMES WHEN IT REACHES OVER 90 DEGREES OUTSIDE, THE MOTOR STRUGGLES WHEN YOU GIVE IT GAS. YOU CAN HERE THE RPMS GO UP.

I have the same problem with my 02 Trailblazer. One shop said it was a transmission issue but when I took it to a shop that works on transmissions they said it was a fuel pump causing the loss of power.

Id maybe try going back to 87 octane gas cause 93 may make it run better but it will run hotter too and that can cause premature detonation and spark knock

1998 cavalier overcooling and loss of power driving


ever change your fuel filter??? them cars are real bad for bleeding air from engine if you say changed the rad, had serious leak and topped it up again.. over cool sounds like you had a previous overheat and the thermostat is now stuck open....thet effects mpg because the long warm up time tricks the temp sensor into thinking its cold . temp sensor is todays choke on fuel injected cars. it tells computor to dump extra fuel....so it can act like its "flooded" some temp guages work both the computor and the dash gage, some cars have two , one dash one computor, new costs around twenty bucks and filter should be around ten

Vibration at idle


it may be idle control sensor or a bad mas air flow sensor--maf sensor in otherwords. or could be engine misfire at cold temp. start. only time when cold? or does run better when warm? try warming engine to operating temperature before driving,if problem removes it's self after warm up,up grade gas to 93 octane for 1 tank full. then see if problem goes away. it's cold where you are right? if so the fuel needs to be at least midgrade 89 octane fuel because 87 octane fuel will not start your honda correctly at cold temps. in cold weather 93 or super gas octane will start ,no problem,low octane fuel sometimes gels, or freezes at low temps. if in warm climate, change the fuel filter, add fuel injector cleaner to your fuel tank[preferablly lucas fuel treatment] this will lube your fuel injectors and give better fuel mileage. thank you for choosing fixya.com

you know what that sounds like it may be.... believe it or not check your trans fluid (car running WARM and in park ) make sure that the fluid is red almost pink like not dark red. Also why not try and change out the spark plugs and air cleaner!

Truck has set for two yrs. i would crank an go around the coner put insurance on it drove a few days later it started running sluggish it kills at stop it cranks right back i put a tune up changed plugs...


After sitting for 2 years, the gas has moisture/water and it's pretty much not gas anymore. It's like your car needs 87 octane and you are running on 80 octane, just enough to fire off but not strong enough to to keep a good idle/firing. I would drain all the gas out and use a higher octane gas for a half of tank just to clean the lines and injectors. Fill the tank up 1/2 with high octane and use a bottle of injector cleaner. This should clear up the sluggish problem. Also it's a good idea to change the oil and run an engine cleaner through. Drain a quart of oil, and pour in the engine cleaner. Let engine run for about 5 min for oil to heat up and circulate. Drain oil and change oil filter, put in new oil.

Accelerating


once you change fuel octane it may run sluggish because the car is used to running at a better octane to run more efficient. go back to 93 and see if that may change it back to normal (note that it may take your car a few runs to get back to normal)
