Ok we were doing about 85 and I down shift as we take off and when I get to about 5500rom the car starts to jerk like a motha but still accelerating wtf. Well I lost the guy is from a "racing team" called REQIUM RACING I know some of them so I want to make sure next time I go up against him I don't fall behind and hopefully win. What can cause this jerky power I had to get to 6k through about 4 jerks then it was smoot but I have an s4 so only Ik left before I shift.

Help gladly accepted thanx, Santiago

 

What are your current mods?

Was it a GT? What year?

 

I think just the regular six cyl. I have beaten GT's before(well one anyways) I removed the A/C, stereo, and switched to a cone intake. My pulsation damper is now a banjo bolt and I have replaced most of my VAC lines with silicone.

 

If this is the extent of your mods you'd be lucky to get low 16s. Sorry but thats not gunna cut it against what you are racing.

 

ehhhh, sorry man. I've lost my share of races, but never to a grand am.....

do some more mods, you'll be happy.

 

What I am getting at is that I have beateng GT Grand AM's before even read my kill on one that was riced out but actually had some borla muflers and K&N intake and a stock on aswell I don't get why my car started jerking like that any possible causes of this and remedies is what I need.

 

does anyone know what the cause of the jerking could be!?!?!?

 

no but if u do it too much you'll go blind!!!


try fuel filter/ lines/ injectors
or it could be ignition... when did u last do plugs/ wires.
this could be all manner of things id say just start with the **** that is simple to check and easy/cheap to fix and move from there. does this always happen or did it just that one time?

this would be the second time but last time I beat an eclipse even with the jerks

 

what kind of jerks? Is it your engine or your actual car? Could it be your tires/steering/transmission slipping somewhere or something? Or is your fuel pump going out? I would take it in to get it looked at. But then again it could be something simple like plugs/ wires...

Not that it really matter but what type of oil you using? Are you running in cold weather?

 

or maybe even your actuators are f*cked. Mixture? just tinker with it

 

dude get used to it, sorry but an N/A is not described as fast either, just fun! On another note don't feal bad, I lost to a Gram AM GTP, supercharged smaller pully, 9PSI, and an aftermarket cumputer, but I only lost to him by, 0.02secs! if I wasn't at the drag strip I sure have hell woulda thought I beat him, that run was my 13.85, the GTP ran a 13.83!!!!!!!!!

 

Your car is jerking probably because you FUCKED AROUND WITH THE TPS SCREW----HAHAHAH

 

Yeah like there is going to be a two week delay.

 

I run mobile one 10w-40 about to do the oil change but it just rained and I am going to wait until the weekend to do it I just came back from checking the plugs and I found out that the plugs that the car had on were all leading ones I replaced them all with the correct ones. Now I have bothe leading and trailing the wires look dirty but I don't have a new set so I can't do that right now. I took the car for a 0-90 rum and it felt a lil better oh and DC350 My idle is now solid at 700rpm.

is it one of the those really rare 87 turbo grand am's??? my cousin has one and it runs 13's but thats with a T03 and like 18psi of boost and some heathy mods to back it up.. just curious..

Supercharged Grand AM GTP I'm sure Pontiac would be interested in hearing about this one.

I think you mean a Grand PRIX GTP.

 

I've seen a bone stock grand Prix GTP run a 13.51 when manually shifted. 15.1's when the slushbox was in control.

Grand Am GT's can be pretty quick if they have the right mods. My roommates `02 dynoed out at 166hp @ the wheels with nothing more than a cold air intake. (not just a cone filter, but mandrel tubing going down in front of the left wheel well) That car weighs 3150lbs and poses a threat to me in first because of his torque and better traction, (225 rubber) but when I hit second its over. Too bad he cant afford insurance on the car now from all the tickets. (he hasn't sold it yet but is accepting offers) I'd like to run him again with my new suspension goodies and see if he can still give me a challenge in first.

 

time slip please

for that 13 run in a stock gtp ?
not saying it isnt fast but 13?

 

We have it on video and I hate the ************ who did it. Needless to say we were all surprized by the time as well. PM "Lechnoid" on here and ask him. He was there that day also.

 

well if you love in mn lets just race

 

put another ground on your ECU and battery...make sure your 6 ports are working properly.

 

I get that in my car too... Let me ask you this:

If you accelerate slowly to redline, is it still there?

If not, it's most likely the TPS.

I only get it when I floor it.
