Hey guys,

I am having some problems with mine and wanted to know what you thought. Today I put in ZZP 1.84 roller rockers (stock springs). I used the method of TDC that after the intake push rod goes down then the exhaust push rod goes down the cylinder would be at TDC. I torqued all rockers this way in pairs. I buttoned everything up and it started but ran rough. I noticed some arcing from the #4 coil to the bolt that holds it on, along with pretty much equal but massive misfires on 1 and 4 (aeroforce). After tracing the wire I found that I forgot to plug it into the spark plug (stupid). Same problems after fixing that. Next I changed to a so-so spare coil and had the same problems on 1 and 4.

I got worried and tore everything apart to make sure it was put together right and was going to re torque tomorrow. Any thoughts you have would be appreciated.

I wonder if it is possible for the board under the coils to get fried because of the minute or so of arcing.

Could it possible be an incorrect ground on the Coil bracket? When I first started the ending I didn't have the bracket tight and I put the ground in between the bracket and the head rather than between the nut and the bracket. I am gonna look closer into that tomorrow.

Looks to be fixed. Just need to get the cover back on and take it for a test drive.

What did you do to fix the problem? What WAS the problem?? May be helpful to those of us considering rocker install in the future in case we run into similar problems..... Glad to hear you got it fixed, Vic

I started the car without bolting the coil bracket down tight. There is a small ground for the coil harness that bolts to one of the studs. All is well now and this coupled with the HV3 actually makes a difference in the car. I am happy with the performance.

Sweet, glad it wasn't anything major like bent rods.

Ready to race yet?

Glad you fixed it. Rockers and an HV3 make a nice performance addition.

HV3? This is what?

lol, Blackwood....

An HV3 is an insert for the Upper Intake Manifold of the L36/L26 naturally aspirated 3800, it wouldnt do any good for a S/C'd vehicle because your supercharger obviously takes place of the LIM(lucky bastard ). Anyway, it basically just creates a smoother, more efficient path for the air to travel within te UIM and into the LIM. Helluva lot better than stock. Anyway, glad you got it fixed Vic, you've inspired me to tackle a rocker install in the near future. i was just kinda waiting for a few others from the 04+ crowd to try it first to see how it reacts to our gen of GP's

I have done motor swaps in older cars that made me worry less, but it really isn't that hard. My biggest worry was having a car this new down because I messed something up.

Really the hardest part is getting all the crap out of the way just to get the valve covers off. After that, the rocker install is a piece of cake.

Yeah. It is amazing at what has to come off just to pull the rocker arm covers. The rear is easier than the front!!!

Not on the 04 at least. The front was off in about 10 minutes but the rear needed more attention. Removal of the belt, alt, coolant part after the water pump. Of course I broke both coolant elbows.

After studying the situation we realized that we only needed to loosen the water pump to get enough clearance to get the cover off. We didn't want to break into the coolant system if we didn't have to.

Now that we've done it, I'm sure it wouldn't take half as long to get the job done. The first time there was a lot of guess work as to what needed to come off and how to get it off without causing other problems.

Agreed, after the first time I think I could get the job done in 2-3 hours tops rather than the 6 hours.

6 hours? holy cow.. i agree there is a ton of stuff to take off just to get the valve covers off.. took me 2 hours the first time.. if i did it again i could do it in 45 min probably... i was surprised that i had no problems at all when starting it up! still runs aesome to his day! the rocker paired with the HV3 and my plog made a hell of a difference. i'm anxious to get a custom tune an get it to the track!

Yes but like HotRod said, there is a difference in the set up for the 04+ GP's. It's much harder to get at the rear rockers than it is for the pre-gens.

Welcome to valve float. It appears the 1.84 rollers / tune from this week are going to be too much for the stock valve springs. I will now need to bit the bullet and get some aftermarket springs.

I am getting a little hesitation and breaking up in the 5k+ range in first gear. What a bitch.

That's wierd, I don't have any float. That was the whole purpose of going with the 1.84's.

In the reviews on ZZP's site a guy commented on having float on his car with the 1.84's. I thought I would be safe, but after a plug change today and no difference I am thinking it might have a hint of it. I even swapped back my ZZP tune and Overkill tune, but no help.

Some time it sputters or misses at the top if 1st gear (around 5700-5800) No actual misfires are recorded. It seems like sometimes it does it and sometimes not. I have the ZZP PCM in right now and it ran normal and chirped second on the way to work this morning. I am going to clean the K&N and Maf today, as it may be something like it is getting choked off at upper RPM, then put the Overkill back in and see what it will do.

Overkill tune is back in and cleaned the MAF and K&N. No trouble on the way to work this morning so it looks like all is well. With that filter behind the fog light it picks up a lot of dirt and the maf was pretty rough as well.
