I just sent mine off to RC Engineering, on monday, called today thursday, and they said they were done and that they would be back to me by friday, total is around $130 for all four, with shipping.



Give me a minute mines all apart i will go take a picture of that ground wire, but my car is a '79 so there are a few extra wires, but everything else is the same as yours

here is a picture of the bolt and ground wire

closer view

yes, sounds like u have bad grounds. Replace them with thicker wires and make sure contact surface is bare, no paint etc. Injectors are $25 a pop at Rc, i had mine done there and i got a pair there right now.. Anyone who is having a hesitation @ 3800 rpms its either the grounds or the secondary injectors.

that's not totally true... yes grounds can be a problem and yes secondarys can be a problem, but i had the same problem with my rx before i re did my exhaust... if the car still has a stock exhaust or stock cats on the car then it is possible that one of the pre cats or main cats is not free flowing enough and trust me 5 out of 10 times this is the problem when you have a 3800 rpm hesitation. when mine happened i replaced the tps because that's what the first thing that read wrong was and then i fixed all the grounds and that wasn't it... all my injectors were brand new on a new motor, and sure enough i put a cat back on the car, and we cleaned out the stock cats and the car was good then about 2 days later i put the random tech cat on there that i have and the car was ******* running great. just thought you guys would like to know because noone mentioned exhaust issues in the thread, and that's what it sounds like to me

well its possible it is exhaust, but there is a bulliten on the ground

Hmmm...Never heard that. Always good to have a new perspective though. Don't think that's my problem. My cats are hollow. Speaking of which, I still need to make that straight pipe to put on my car...

well, soon I'll be replacing some exhaust, so I'll see how that works

mine feels like its gonna die when i am drifting it around 25-30 mph, i thought i didnt have enough gas and when my car goes sideways, it doesnt get enough fuel.

so what do you guys think. i rev my car during drifting around 4-6k.



so it could be the ground, injectors or the cats...

I was just going over this post and sounds a lot like what's going on with my rex. Im going to try the grounding solution to see if that work.



My motor sputters when its at idle. After it warms up it starts to smoke around the exhaust manifold. now this is a j-spec motor that's bin sitting dry for 2 years im just getting a chance to use it and im getting this. I haven't had the car on the road yet so see how it will power the car. https://www.nopistons.com/forums/pub...1047683358.gif
