ok soooo how do i start i was driving my fc se model and one day it take a couple roll overs to start, and then when driveing it it cuts to like galf power and kills if rpms get to low then i keep thwm high it goes back to full for a little bit and switchs back and forth, than it kills for good after a wile, the only way i could start it is if i put gas in th throttle body and then it runs like butt. gotta keep th R's up and it will kill, i got fuel pressure compression and all that, i changed the MAFS and it worked a little bit but did it again help me please is it a bad ground connection or pos another bad MAFS (mass air flow censor)??? help and hints plaese will also answer any ?'S u have about the prob

 

how many miles on engine... it kinda sounds like it is blown.

get a compression check or do a search for blown motor. see what kinda info you can come up with.

 

Bloat injun. That Censor probably black lined it out.

 

ya i dout and hope its not blow why whould it switch from fulll and ok for a houre or 2 then cut out

Honestly, I'm having a hard time understanding what the **** you're talking about.

 

haha ya ummm im driveing right norm and runs good, then boom a huge backfire and it cut to like half power for a bit then goes back to norm for a little bit, asfter a day or two it wont start unles i put gas in the throttle body. get a new MAFS and runs ok then after a bit strts acting up again and dies again after that HELP im doing searchs and please no flame and i need help as soon as pos

 

Ugh, I'll ATTEMPT to translate.


"I'm driving normally and it's running good. Then, for no apparent reason, it backfires. Along with that, it cuts to half power for a while, then goes back to normal operation.

After a day or two (of sitting?), it will not start unless I put gas (what kind?) into the throttle body.

I put a new MAF sensor on and it runs ok, then after a while the previous symptoms occur.

Please help me. I'm attempting to search but it isn't helping. Also, please don't flame me even though nobody can understand my posts. I would really appreciate it if I could get help quickly."

 

exactly thank you im not good with writeing and or typing, after a day or two of driveing and its 90 oct gas thanks for tranlaiting

 

+1.....

So you did a compression check? what were the numbers per rotor face?

as far as idleing goes, have you checked the TPS?, looked for vac line leaks? you know the simple stuff?

But you really need to work on typing clearly I seriously have only a very vague idea about what your problem is.......elaborate please.

 

how do i check the tps and yes comp. and yes spark and yes furel and did not find any vac leaks

 

Would it be possible for you to slow down and try to make things clearer? I'm not trying to bash on you or anything. It would just be a lot easier for people to help you if they got the right information in an understandable way.

Anyways, you can check the TPS using a multimeter. If you search there's threads on how to do it. Or you can use the FSM way.

You say you tested for compression (I think). What were the results, as asked by classicauto?

 

found prob coil going bad ( switchs on and off) close tread thanks for help and patience
