Thread: My Grand Prix randomly gets lazy.....

Hello, recently my car has been going limp..(not where it actually says reduced engine power) as it takes way to much to get get going not as in trans wise but as if the motor is bogged down ... it just feels lazy as if its not all therr no codes... I just recently put in tr55s could it be a defective plug or wires ? I will try to catch it on video.. when I really open it up... it feels extremely slow and civic like... idk im a worry freak but any input is awesome thanks... also when taking off from a dead stop sometimes my kr spike to 10-12 false im sure but could this be retarding the timing way to much hense the laziness?

Clean the TB and maf.

Wasn't the car throwing a p0420 code recently? A bad cat will cause the cat to be sluggish.

You can also unplug the maf and see how the car runs.

Its really random one second its fine which is 90% of the time and then pppppppbbbbbbp it just runs like crap its really poor once the car shifts to second it just bogggggssss down badly s/c whinning n all

And I didnt get any code recently at all I will scan tomorrow again

Was it you that was mentioning your mpg decreasing drastically?

No but my mpg is garbage 18.5 combined

I suppose I will clean tb, and maf but I had the maf off nit even a month ago when putting on the intake and it was clear

U better lol



Start off simple and cheap then we"ll go from there if further t/s is needed

Its just strange why would it only do it sometimes... its random my car is sick... im sad

Because old car lol

Its not even old lol 6 years isnt that only ... you ass lol

Yea it is. They don't even make your car anymore

Hahaha your so funny ... nor do they make yours so technically yours is older than mine... BAM

But mines faster ^_^

And technically they stopped making comp g in 05 so yea it's a gem

May be faster... but mines still newer lawl jp dude I appreciate your help... really any realistic ideas what it may be ? Im a worry wart and im drunk so that doesnt help lmao

How many miles does your car have anyways?

Since the last time I drove it which has been awhile lol like 88k.


You check the things I suggested also the knock sounds like false to me could be worn motor mounts causing the engine to move.

Its not your dd? Whats your best slip?

It was for awhile. Not sure never bothered tracking it. The local track closed years ago and every other one is 2+ hours away and not worth it to me in case something brakes then I'm stuck with a expensive tow bill.
