Hi, i have a camaro 2000, V-6 3.8, and i have a problem, i acelerate and my car donīt responde, it starts shaking, when i start the car and its in idle it runs like if i put a big cam.... and its the stock, about a minute or two minutes later it fine.... but then when i tried to put drive and move the car it lose power, if it in neutral and i acelerate the car it seam to be ok..... please help....
i have change the spark plugs, and the coil pack,......

 

you said you changed the spark plugs and the coil pack.. did you also do the other usuals like plug wires , injectors etc., for a miss

as the plugwires are common

 

no i havenīt change them, do you have a recomendation for what type of msd fitīs my car, cause i have to buy them in summit racing or parts america, so they will send them to me here in guatemala

 

Do you have access to a scanner? If so, put it on a scanner and see what cylinder is registering the misfires. Then swap the plug, wires, injector, and coil pack one at a time from that cylinder to another and see if the problem follows. If it does, you know that particular part is defective.

 

they put the scanner and it give us p0300, and donīt apear any more codes.....and i find that p0300 is random.....

 

These are the MSD wires that come up for your application: http://store.summitracing.com/partde...143+4294840137 I would also check over the car for any vacuum leaks. The plug wires may not necessarily be bad either, they may just have loose connections. It wouldn't hurt to make sure they are firmly seated on the plugs and coil packs.

 

yeah defintely a vacum leak could be.. other thing in the back of my mind was fuel/air??

it sounds like just a code reader that you are using.. the scanner should give alot more info than just the code (it should give all sorts of live vechile data).. you could take it in to a shop and have them do the full scaning but it'll probbaly cost about the same as the set of plug wires... and we all know on the 3.8s the plug wires do go wear out reguarrly so I'd probbaly go ahead and swap them first as it really can't hurt, but I geuss it really depends on if you want to drop the $60 on soemthing that may be a "geuss"...

isn't there a way to check the resitance on the plug wires... something like take them completley off the vechile (one by one) then test reistance from plug end to coil end??? anybody know the details

 

thanks to everyone, i all ready pay for the msd plug wires in summit, i gess will arrive in one week..... in the mean time..... iīm taken te car to a shop and, they have the scanner, the check all the sensors of the car.. i hope we found the problem there.... when i got an answer i tell you

 

glad we could be of help.... on the car if it's not urgent I'd wait on intstalling the plug wires before takign to the shop to do the scanning.. as if the plug wires fix the problem then no need to pay the cost for the scanning

 

hi... again.... well let me tell you... today a recibe a call from the shop... and i have a vaccum leak,... in the brake booster... i need to change it.... thes said to me that when take off the vacumm hose of the brake booster and close the hose... they reset my ecm and my misfire disapear,... but i have another problem ..... they push the gas pedal and the car wont accelerate... sometime more is worng.... today they are going to check fuel sistem presure and a lot more..... do you have and idea that could help me fine what is wrong?

 

Hi, all.... well let me tell ya... cause my brake booster has a leak it damage my cat conveter (cause of the misfire),..... it broke down in pieces so my exaust was clogged... no wonder my car can not accelerate... so if this is anyhelp i share the story.... thanks to all of you guys for the help.....

 

Did you get a SES light due to the cat not functioning properly?

 

nop.... i dont get SES light, it should.... i donīt now why it dinīt came on

 

the cat... was broke in pieces inside.... so it clogged the exhaust... but no SES ligth s....rare... is it?

 

Considering there is a post cat 02 sensor that monitors the catalytic converter's efficiency, I would have expected it to post a code.
