KA24E bogging,fuel issue?,IDK

[dat925stunna]

ok look today i took the car on a long drive and high rpm it boggs down to 3k then its kool but if i down shift sometimes itll red line then wen i go from lets say 3rd and shift alil above 5k then 4th and i get to 5k and nada my foot all the way to the floor and nada like if i turnd my car off on the highway then as my foot is still down the tach neddle is @ 3k and car responds again then 5th and usaully in 5th im doing 65-70ish mph@ 3k RPM wats my issue VSS? EGR?

Speak english...learn some grammar, man.

If you're having bogging problems, you might wanna try testing your MAF sensor.

bro already did that been done

Sounds like fuel pump starting to go bad. You need to check fuel pressure with driving on the road. Should be 40-45lbs pressure. It is getting lazy and dropping pressure at high rpm. That's where I would start.

well the speed sensor code came up so ima fix that and see if that fixes that

[rioredstang]

No I did think that would have any effect on the bogging issue. I still think you have a fuel problem. I would test things first before buying parts. Start with fuel pressure first, then test maf sensor. Yes you should fix the speed sensor, but this is not related to your problem.

[ShouldaHadaV8]

could bre the fuel pressure regulater! im doing all my fuel issues, cant get power to the fuel pump.

[allenms240]

hard to understand what your problem is?Is it bogging out on high RMS?Its fuel related then, there isnt enough fuel pressure getting to the motor when the RPMS are so high.Perhaps the pump is going out as mentioned above.

I'll explain it better because My KA24E hatch has the same issue.

When you're driving on the Highway in 3rd to 5th gear. Once you are above 3200RPM. the computer will only let you have 100% open throttle for 5 seconds. After that five seconds, The motor cuts fuel off until the RPM's return to 3200. I'm researching it now because of my similar issue.

You probably don't have any sensors hooked up on your transmission. That's my problem. I have no sensors hooked up on my motor. it's throwing codes and it's shutting your car off so you don't go too fast. The computer thinks you're trying to override something. So it cuts you off. I'm working towards a solution now.

[rioredstang]

The computer doesn't think it only does what its programed to do!! With that said, if you have codes, fix them first. If the computer loses a sensor it has default modes that it will operate in which are rich, and retard timing.

Diagnose the problem first before replacing any parts.

Check the basics. Check and set timing. Install fuel pressure gauge and test drive the car and verify that fuel pressure is correct.Use a dvom meter and test sensors. The factory service manual has the sensor ranges listed. Use the link below to look them up. Many parts stores will loan you the tools to test with.

Diagnose the problem first. Don't listen to our guess's and just go buy parts and waste money. We have a wealth of knowledge to give you but we are not there looking at your car so we can only advise on how to fix. Its up to everyone to learn to use the FSM to find and fix your problems.

um i checked the sensors I notice my reverse doesnt work cuz my white lights dont turn on and one sensor has cut wires? but the speed sensor circut code and egr code?

[dat925stunna]

could bre the fuel pressure regulater! im doing all my fuel issues, cant get power to the fuel pump.

could bre?

so wat swap it out for a 255? cuz im gonna turbo my lil ka

[brokeded]

and your gona blow it up, because if your seeing cut wires and running it.....................you need to learn what the hell a soldering iron and some heat shrink is. good luck

im gonna blow my motor if my transmission sensors are bad?

[sx moneypit]

Thats bulls**t,they are not going to cause your engine to blow up.

[Coupe_Devil]

dat925stunna, It's not a fuel issue. It's a Sensor issue. does your speedometer even work? Turboing a KA24E? You're going to blow the motor while it's throwing codes. you have to be precise when trying to run a good turbo setup on Any KA. Good luck

rioredstang, First of all, you are a Grammer Nazi. What term I use is not important. Secondly, dat925stunna needs help, not me.

yeah i kno man

[rioredstang]

You don't have any sensors hooked up but you don't need help! What the h*** is a Grammer Nazi anyway. I clicked on the wrong reply button. Good luck anyway.

[brokeded]

no i meant be careful with the turbo, and to sx money pit........................f u c k you

Warning 2, when I find 3 your on vacation.

Read post. I think its-MAF related, Feul pump or FPR related, or even o2 related.

[locoluna825]

All you REALLY need hooked up is your speed sensor to make this little issue to go away.

[sx moneypit]

Thank you Kevin!

where was my first warning at?

hey wat about a auto sohc ecu?

[locoluna825]

hey wat about a auto sohc ecu?

^That will do it too. A Friend of mine has a real manual 240, his speedometer went out and the car would cut out at like 4500 rpms. we switched it temporarily with an auto Ecu to make it go away until he got his new speedometer.

If your speed sensor is unplugged you will get the same issues as you would with a bad speedometer.

i have a similar issue i didnt wanna start a new thread though and have two of the same...i swapped a sohc ka24e into my 200sx (s12) and had a similar issue and i was thinking this was the same thing because it cut out underload in 5th gear so i was thinking no vss it was cutting fuel.

i used the s12 trans w/ ka bellhousing hence i dont have a s13 vss hooked up. i have the typical cable driven speedo drive gear. so i tired the auto ecu and the problem went away my question now is there any adverse effects of running a auto ecu on a 5spd car? does it run richer or leaner is the timing retarded or advanced. thanks for your help man. the motor is strong and healthy i dont wanna blow the engine later on. the car drives fine now. the only reason im not running an actual s13 ctrans is because you have to cut the floor pan as a s13 c trans is longer than a s12 c trans so i just swapped bellhousings to make it more (bolt in)

any help would be appreciated thanks!
