Engine dies when warmed up

[ilovecoupes]

Okay got my CA running decent except when I take it out for a little. And warm it up, then pull the car into my garage, and let the car idle for like a minute or so and let the turbo to cool. The idel starts to go lower and lower and if i give it some gas to bring the rpms up, the engine has no throttle response, kinda like its missing.

when is cold or a little warm it runs fine

Temp sensor?TPS?

thanks Joe

vac. leak or boost leak timing did that to my car.

[Indecisive]

I had a similar problem where my car would stumble and not idle properly after it warmed up and not drive properly either.

The cause of MY problems were bad ignition coil(s).

I replaced those and it was fine after that.

my spark plugs are a little white so i guess ill throw some new plugs on there and see if it helps

okay changed the sparks plugs did't do anything. can't find any vacuum leaks.

so it sounds like it is either my coilpacks or timingany other ideas?

get a cheap timing gun and check where it is. u could even use the timing gun to see if any coils arent getting spark

ya i already planed to get one tommorow

didn't know it also tested the coils for spark

thanks for you help

okay turns out my timing was waaayyyy offso right now the CAS is maxed all the way to advanced.i checked the timing belt and gears: all the white dots line up where they are supposed to be.

so is the cas bad?but also im running lean, but that can be due, to the fact i have a 255lph fuel pump and stock FPR

a faulty coolant temp sensor will cause running problems when the car is warmed up. try replacing that, its cheap, and could be an easy solution.

A KA one should work, so if you still have your KA, try replacing it with that first.

It seems to be running fine now, with the current sensor. but my problem now is that i have the CAS maxed all the way to advance and it is still off. its at about 25 - 30 degrees BTDC

how are you setting timing? what are you using for your timing light? what I'm trying to ask is if you're setting timing correctly as shown in the FAQ's...

I set it refering to the FSM. I have an old sears timing light my grandfather gave me. Im trying to get the 4th eched mark on the lower timing pullie, to line up with the little arrow on the lower timing cover. I aslo have a dwell but have noooooo idea how to use that.

where are you getting your ignition signal from? the fsm says to use a nissan only tool from what I remember.

from the first coil pack. I got a spark plug wire, put one end to the spark plug the other to the coilpack and cut a little piece of rubber insulator off, so there is some bare wire, and hooked my timing light to that

<3 perfect, well done. have you counted the teeth between marks on the belt, or are you just relying on the painted lines on the belt itself? double check that. I'll keep thinking... you're doing timing correctly, your belt is on right, might be your CAS I suppose. You have another CA owner near you willing to loan you a CAS to test out?

I counted the belts teeth between the each gear. Im pretty sure im doing everything right. The nearist motor remotely close to a CA around me is a RB20.

how bad is it to be runing 25-30 BTDC?

[NeedCAforS13]

I don't think you'll break anything (I could be wrong), but performance will suffer greatly. RB20 CAS isn't the same from what I remember. I know had a friend try to use my CA18 one on his RB25 and it wasn't the same.

I'm kinda stumped too man. If you're 100% sure the physical cam timing is correct, it kinda has to be the CAS or your timing light. Maybe try another one...

[ilovecoupes]

ya i figured they would be diffrent. I do have a Dwell, any idea how to use it? the fsm says to disconect the connector for the tach, looks like its near the battery, any ideas?

thanks for your help also NeedCAforS13
