HELP!!!! Please!!!

[1997_GST]

Hey guys... Ok well I swapped my 7bolt motor into a shell with my wiring haness and everything.. Well now I can't seem to figure this problem out!!!

When the maf sensor is plugged in, it won't rev past 5500 rpm and acts like it's fuel cutting or something.. Whn the maf sensor is unplugged it bogs and then when it revs it'll rev all the way up to redline... I just got a new maf sensor so I don't think it's that...

Can anyone help me?!?!? It's driving me crazy!!!

Thank guys.

Any Cels?

It could be a hole bunch of things, as poonman said is there any codes and have you checked for boost leaks? Also make sure everything is pluged in and in the right spots.

Yeah.. The obd2 scanner tells me like a bunch of sensors are bad and air to fuel metering .. But some it said was are new such as cam angle sensor, maf, map, and coolant temp... And I know it's not my ecu cause I borrowed a friends and it did the same thing.. I was told that it could be cause of plugs and wires..?? I checked for vacuum leaks and I can't find any and the vac on the boost gauge is normal...the only thing I don't have hooked up are fog lights and side marker lights.. And everything else looks like or only goes to one place... I'm stumped!!! Lol

I would check your o2, your o2 can rev limit your car. I've seen it happen on a lot of cars. But be more specific, when you get to 5500 does the car cut up or more like a stumble.

Is there anyway you can do a video i.e cell phone, camera or something. It would be nice to hear it.

 

[1997_GST]

I can.. But i'm not sure how to upload it to a thread with my iphone... And that's my ony way of Internet... Can I get your email so I can send it that way??

 

[poonman]

Sure I will upload it for you if you send it to me. [email protected] or [email protected]

 

[1997_GST]

Give me a few min.. I'm going to take the video now

 

[poonman]

No rush, I'm going to lay down. Its 12:30 am here. But send it anyway and Ill get it posted for you.

 

[1997_GST]

K I sent it to the eclivic one... Let me know what you think.. I appreciate the help!!

I would check your fuel pressure now.

 

[1997_GST]

How do I do that?? I don't have a fpr...

I mean I don't have a fuel pressure gauge.. So how do I check it?? Can you without a fuel pressure gauge??

 

[poonman]

you can use lots of things as a gauge, Ive used a bike pump once, anything the fits on the nipple and pushes the needle in.

Could timing beingboff cause this?? And also wouldn't I throw a code if timing was off?? Also I put in new ngk spark plugs and now only 2 cels are present, p1104 air/fuel metering saying something about the wastegate solenoid or something?? I read that it gas to do with the stock bcs but that's not on my car and wasn't on my last one and I didn't have thus problem.. And the second code was o2 sensor bank 2, which I know is cause I don't have a rear o2 sensor but I didint before I did the motor swap and it ran fine.... Any other suggestions?

My 1st Gen did this and it turned out to be the MAF. Try cleaning it.

 

[1997_GST]

Ok I'll try cleaning it... I'll let you know how it goes..

 

[1997_GST]

Hey... okay... so i got a new maf and the result is the same...

but... this is weird...
if i un plug my mdp sensor and put like a test light on the 1st terminal of the plug it changes idle and itll rev fine??? but i read that the mdp sensor is not important.... IDK im going to try new plug wires and if that doesnt work i guess i gotta take it to a shop... which i hate to do but i need my car running!!!! >-/
