So, I relocated the IMRC to under the open air filter like people here recommended. Then I added a rubbermaid trash can heat shield just like the ones I've seen pics of on this site and it still dies out once it gets hot.
When I pull over and rev the motor by hand I can see the IMRC cable jerk, and the filter is quite warm to the touch but way way cooler than anything else under the hood.
However, none of these mods seem to have had any effect on this problem. Also I took the car in for a diag a few months ago and they never mentioned it throwing any codes or anything.
What gives?
put in a new fuel filter if you haven't changed it yet. Check your fuel pressure to make sure the fuel pump is functioning properly.
Other than that, there is a linkage that runs between the two banks of the Lower Intake Manifold (LIM). The plastic clips/retainers will sometimes crack & crumble & the linkage comes apart.
I had a mechanic change the fuel filter during the tune up/diag when I got the car a few months ago and so I assume he checked the pressure as well. Also would that and the linkage problem really be problems that only show up after driving long enough to get the hot very hot? Same with a fully broken IMRC, right? That would mean the car is always slow right? Not just after driving a while.
Just for clarification, the car hauls ass right out of my garage and then dies off some 10-20 mins later.
try cleaning your LIM's? maybe the secondaries are sticking after they get hot?
also, make sure your spring is on so the secondaries return when they are released, and if its intermittent IMRC box, open it up and clean it with electrical contact cleaner. and FYI guys, there is a nice heat shield that pep boys sells you just have to grind one side down to the contour of the strut tower, and make the hole a little bigger ifyou have a K&N. do this, it's aluminum, and you wont look like a civic tuner
heat soak, gone! lol
Yeah from the sounds of it I would think there is a larger problem. How about wires/plug/coil pack condition? I saw you had a tune up, but did you replace wires/plugs? Once those suckers heat up I would think it could cause problems.
Could shot tranny fluid also be an issues? <-- that might be out on a limb, but if the fluid is toast, it would probably cause issues after heating up for 10-20 minutes.
the best place to mount it is under the battery. if that doesnt work get a new one and mount it there. i mounted mine with zip ties under the battery and its been on there liek that for a few months now. at first i had it with a bolt the bolt rusted out and the imrc dropped and was dangling on the tranny .i get a 1518 for the runners being open but they arent even stuck open. i guess some kind of sensor in the imrc isnt working right.
i put mine directly under the battery. its zipped tied to both bottom sides of the battery rack. if your imrc isnt working at all you need a new one. if it works than stops workign after the car gets warm the relocation should help. my original imrc had got to the point where once the engine got warm it wouldnt work untill i shut the car off and start it back up and it would cut out again. than when i relocated it it was all back to normal. but i had to buy a new imrc once the cable had ripped.
