crazy studdering while Reving

[Pimpin Dsmstyle]

My buddy just went to do a stupid tune up on the car. Replaced filters, changed oil, did some free mods.. everything was working fine. A couple days later, he decided to swap plugs and wires because he broke a wire doing a comp test and the plugs looked like they were the stock plugs.

It was running fine for about 10 minutes of driving. Shut it off, came back about 10 minutes later, and bam. At idle it sounds just like a beat.. you could here like a heart beat of exhaust. It was anything but a constant exhaust sound. Then we started moving and noticed it was studdering really bad. It is slower than an N/A dsm I'd think. I really dont know what happened.

He used the correct plugs ( bpr6es or some shit) and some cheap ass wires. Xact or something shitty along those lines. This car is completely stock ( 1g tsi AWD 7 bolt 92)

Any ideas anyone? Its friday, I probably wont get much help heh.

Sounds like a plug wire could be loose on either the plug or the coilpack.

Or some shit? There are a lot of plugs that are simular numbers but arent the same thing, if your not paying attention you could get the wrong ones. BP6S BR6ES BPR6ES. Make sure he has the right ones. Cheap wires could be the result. Make sure you have spark in each cylinder, if so then move to fuel. If no luck still check the intercooler piping, you said he replaced a filters? Was the air filter one of them, did he unplug the mas sensor and forget to plug it back in? Might try throwning the old wires back in, see if it helps.

Wow... 92 to have a 7 bolt. Not many of them were made. Interesting to know one is in the Metro area.

I would have to say a plug wire came off or is not connected all the way. Check the Mas plug also.

Bullshit, I would bet that either the plugs arent' gapped correctly or they are the wrong plugs. Brand new wires even if they are shitty should deliver enough spark on a stock car. What did he gap the plugs to?

If I remember correctly, the late 92's got the 7 bolts, didn't they? Mine was built in late 92 (93 model year) and had a 7 bolt in it.

Of course we can't forget about Mike's 93 with a 2g 7bolt in it........

I am going with Craig. I bet the plugs didn't get gapped and are sitting at .032" gap. If that isn't it, then one of the plug wires probably came off.

Very late, because 7 bolt production dates were 5/92 and up if I remember right. Usually any vehicle with a production date of June or later is the next model year. So there is a small percentage that were 92 model year with the seven bolt.

But would a .032" gap do that? Isn't that what they are supposed to be stock? Shit the guy that owned my car before me had his gapped at .035" so he said he could run 90 octane without any ill effects.... But I never had studdering problems with that gap, for the three months they were that way.

Yeah, I got to thinking about that and a big plug gap shouldn't matter at idle. A wire probably fell off. The plug gap matters more under boost.
