issue with Ka24de

[chanklas]

I have this issue with my dual cam, the issue is when i start the car it runs and idles fine. But when i take it for a drive the engine wont rev past 3500rpms. if i give the engine full throttle it makes this gargling sound from the intake. Sometimes it will rev high but it looses all torque and makes the gargling sound as well. I have replaced the MAF sensor, Knock Sensor, TPS Sensor, 02 sensor, The Coil, Spark plugs, Ignition switch. I have a walbro in the car and did a hot wire so it gives the fuel pump more power and flows more fuel. Im at the point where im going to do an sr20 swap. Ive thrown to much money trying to figure out why this dual cam wont run right. Since i have this issue. if i move to an sr20 swap will the same problem accure? I could use some help please

[biggie]

Still sounds like maf issue check wiring on maf. Next I'd swap ecus to see if that's it.

[chanklas]

Im planning on going with the sr20det. But will this issue happen again when i do the swap or could this be an issue with the ka harness and ecu?

[moso]

sounds like the maf or maf wiring is bad. not reving past 3500 is a dead give away. check the ecu for codes then check the maf wires for continuity to the ecu. if the sr has a maf problem what will you do, swap in an rb?

[chanklas]

Luckily I have lifetime warrenty on the maf sensor. So ill try a new one and check continuity on the wires. I plan on doing the sr because the engine has a bad noise in the head and im to lazy to pull the engine apart. I've been planning on the sr for a while.

i wouldnt be a bit surprised if the noise in your head was nothing more than the chain guide.

[chanklas]

The noise comes from the intake side of the head ill have to start and run the car real quick with the valve cover off

I didnt change anything in my ka24de and it use to gargle like that at 3500 rpm and , misfire , i fixed it by takeing my injen intake out cleaning it , looked at the hoses and they werent so tight and figured out i had a vacum leak causeing it to do this , double check the vacum hoses . mine runs fine now

[chanklas]

Oh ok ill check that out thatnx. Yeah it would back fire and it would back fire from the intake also.

sounds like a similar problem i am having. i took a video of it. ignore the random music interruptions but look at this and see if you have this same problem. plus its intermittent and doesn't happen all the time. i got stuck on the highway when i took this vid.

[chanklas]

Thats exactly what my car is doing.

[clash_ion7]

did u ever find a solution? i've had to pull over twice today during my daily commute and its killing me!

[chanklas]

No I haven't I've changed so many sensors and spend so much damn money its not even funny. Im planning on just going sr. The only possible solution that could solve the problem is going aem ems and turing the engine into speed density and mmap.

[clash_ion7]

geez that sucks. i saw a post where one guy replaced the fuel pump with a similar problem went away but his final outcome was not conclusive which seems to be what most of these threads are. I'm just gonna focus on my SR swap n not waste anymore money on this engine

[chanklas]

Im going to try a different ecu to see if it makes a difference. if not then im without a car for a long time

[clash_ion7]

did u change out the igniter box? I'm not sure if thats the exact name for it. but a buddy of mine who knows a tech at Toyota was like a master with Nissans and Hondas, he said that the igniter box is an issue that comes up and can cause this issue. its located along the engine wiring that leads to the dizzy.

[chanklas]

You mean the coil pack. Yeah I've changed it out did the same thing. I took my car to one of my friends who has a ka-t s14 and he looked at it. He told me to change the whole distributor and engine wiring harness. So that I don't have any bugs in the harness. He had the same issue before in all 14 240sxs he's owned.

might be a bad cat

yea i'm guessing thats the same thing. I'm honestly not 100% sure. I will check again, but basically its an issue going through the wiring harness etc. so all that is advised to be replaced. which I'm sure isn't cheap

[chanklas]

I don't think their to expensive I got mine from the junkyard

[moso]

ignitors and coil packs are not the same. the ignitor is the little electronic sensor looking doohickey on the coil pack mounting bracket.

[chanklas]

I read it wrong. Yeah the ignitor sits on the coil pack bracket. The coil pack and ignitor are two different things.

[clash_ion7]

any updates on this? i saw on Zilvia where a guy replaced the ground wire from a harness that connects the TPS and CTS. check this out

Im almost positive it has to do with MAF. I just had this problem, luckily i had an extra one. I changed it and the problem was solved. Since you have already changed yours and still have the issue, try contact cleaner and dielectric grease, then trace down the wires.

[lexcrob]

I swear i here maf cryed out more often than anything. Honestly it should be the very very last thing you ever replace. Thats after you clean it check resistance verifiy all wiring and do a tap on it with a wrench test! Check you base timing and idle speed look for vacuum leaks and make shur your air filter is far enough away from your maf. Attempt to replicate the factory location to air box. Last but not least o2 sensors and grounding issues as a whole are commmon on other makes and models to cause these problems.
How many of you guys have aftermarket intakes.....



To the OP just unplug stuff till it runs good enough! Start with the throttle position sensor just unplug it and drive it dial in your idle speed! Try other sensors....just tryin to get ya running at least not a fix and your gas milage will suck

[chanklas]

So, its been awhile since ive posted here, and i have replace my MAF twice with autozone remans and the problem keeps accuring with the car not reving past 4000rpms and the car sounds like its retarding timing when i give the car full throttle. I check the codes on the ecu and the same codes keep coming up. MAF and Igintion signal primary. I dont know what else to do. I dont know if this could be a problem but the maf is a 93 nissan altima reman MAF.

[clash_ion7]

i love how no one has found a serious definitive issue to this car issue. *sarcasm* i'm redoing my entire fuel system because after the throttle cutting out issue and eventually cutting of it sounds like the car isn't getting fuel. So once i complete this [one last part] i will have replaced fuel pump, fuel filter, and fuel pressure regulator. only thing i haven't done is ran a separate hot wire directly to the pump. if the issue doesn't cease after this i will run the hot wire to the fuel pump so its always on with a switch.

[clash_ion7]

Hey i finally got my car up n running again after the complete fuel upgrade n it still has the weird idle. But today i noticed something weird. The crank pylley was wobling. I think that may b the issue now. Anyone else got the same problen n gave their crank a good look?

[chanklas]

I solved my problem to on friday. It ended up being my walbro 255 fuel pump was burning out due to loose rust being in the tank and clogging up the fuel pump strainer and my fuel pressure regulator was weak. I reccomend anyone who has the issue with the engine not revving past 4000rpm i would check your fuel system before moving onto anything else. The engine revs to the moon with no hesitations.
