Re: Stroker Problem

The pistons and ring were done correctly. there was so much fuel that it was getting past them.

we made the MAP adjustible. This is what most of the stroker guys do. several of them do it.

the readings for the vacuum is steady, and there is no leaks. traced every line nothing wrong with any of them. breaks were awsome when we first had the jeep then had the motor rebuilt and the cam takes away from our breaks so they are little soft now.

my bf actually picked out the cam and done a lot of reasearch on the build before we actually built it. But like i said before we think the cam is the issue b.c he did get a a mild cam i believe. ( this is my first time with a motor build..so i'm kind of learn stuff as i go so please excuse me if i dont always make complete sense)

when we first built the motor we drove it it was fine, then started to get rich after that...before we finally parked it the jeep ran awsome..did everything i wanted, had awsome power...just lobbed real bad from the cam

we have not sea formed it b.c right before the build had a new exhaus put on

we had the stock throttle body on the first time, and right after the build, still have same issue so sent it off to have it bored


i will have to get all the specs from the BF unforitly he works days i work nights. so it hard to talk, plus he get little cranky when it comes to this jeep as we have so much money in it and it just sits around. Like anyone would do i guess but as soon as i get more info on specs ill post them for yous.

Thank you so much for all the help no other forums are even will to try as much as you guys have.. plus most see i'm a girl and just think i'm dumb...might not know as much as most guys on here but i'm learning...Thanks again!

Re: Stroker Problem

Stupid question, but have you considered running a vacuum canister instead of swapping the cam? I'd try that first. Its alot cheaper and easier.

I would put this back to stock, if anything just to remove a variable out of the fix it equation. You are not running forced induction (going into a boosted state) so the stock map settings should be fine as you are still operating in the vacuum state. The new larger injectors will do all the compensation work (fueling) for the engine as they run in milliseconds open. A larger injector will flow more fuel than a smaller injector in the same set time frame. Therefore your stock fuel tables will be ok to use. The trick is getting the correct size injector to meet the new fuel needs.

I run larger injectors using my stock MAP and stock fuel tables in the vacuum state. When in a boosted state my MAP is "clamped" to a set voltage reading and then the iEMS3 takes over all engine parameters. My engine is stroked, cammed, bored, boosted...everything.

That's the cams overlap causing you issues. To much overlap for your application.

No worries we all start somewhere. The cam may be mild but the overlap is what is causing you your issues. Reduce that spec on your next cam and it should be fine. Please post specs on your current cam though.

If everything worked great at the begining it makes me wonder what happened to cause it to run badly. Please get some Sea Foam and let the vacuum line suck it in while holding the rpm's around 2k (follow directions on the can). I think you have some exhaust leaks possibly around the O2 sensors or before and it is allowing "outside air" to get into the system. The O2 sensors will see this and think the engine is running lean, when in reality it isn't, and dump a ton of fuel (max 33% more). This will be a false lean condition and could be the cause of your fuel washdown. To much overlap from your cam added to this issue as the overlap allowed fresh unburnt air to pass in through the intake valve that was open and right out the exhaust valve that was also open. If you have a leak Sea Foam will find it...Do it outside! It smokes like mad.

Did you go through your entire exhaust system after your initial warm up and then again after around 5-10 days of good driving. New exhaust systems will shrink a bit to their final size after a few heating and cooling cycles.

See what I said above.

Do you have another stock throttle body? I'd try to remove as many variables as possible until the problem is figured out and then add mods a step at a time and move forward in stages. This way you can see what each mod does and if there is a issue it is easier to track down/reverse.

Re: Stroker Problem

okay can not find the specs on the old cam.

okay so we put a new barely above stock mopar cam in. seem to help with it running as rich still a little rich. now it seems to have horrible shake to it, and running like crap. thought maybe timing but that was triple checked and no issue there, then maybe the hermonic balancer. but again fine.

We did find a crack in the knock sensor which we are going to replace soon. as we know that can cause issues.

But with the new cam still not a lot of vacuum.

also the ballist resister is extremly hot to touch. that is not normal. what would cause this issue? any ideas?

we have had several people look at the jeep and everyone seems to be stumped as to what the issue with it is. S

I believe my jeep is cursed. Since day one its been nothing but problems...

SOME ONE PLEASE HELP ME!!!

Re: Stroker Problem

we put the bigger injecters back in and now it seems to be running correct but just rich. so we are getting new stock injecters to see what that does. but it still has a bad vibration any ideas what that could be?

Re: Stroker Problem

Do you have a AFR (air/fuel ratio) gauge hooked up to it? If so how rich? Is it just at idle or under load?

Can you take a video for the vibration? It could be almost anything. Have you checked the motor mounts?
