[DRTY14]

been rebuilt after a blown head gasket back
in my cefiro ,it started fine idled perfecty
but would not rev past 2000rpm , runs
smooth no splutering ETC . . hoping some
one can tell me whats happening here been
told its electrical / a sensor , maybe knock ,
TPS or ECU could still be in limp mode

please reply if you can help

Make sure the MAF is functioning properly. That kicks motors over to limp mode most often.

make sure everything is lined up on the timing side of things

yes this is what i think the problem is as the CAS is
very tricky to get right iv found with my motor ,
and scince playing with the CAS its not even
starting now

the block was decked and head plained from
blowing the head gaskit could this be
contributin to the problem ? a four layer steel
gasket was used , bearings ,rings etc . .etc . .
refreshed

thanks guys let me know what you think

If your timing is off, it'll just misfire and have low power production. If you're having issues getting the CAS lined up properly, make sure the motor isn't 180 degrees off. I've had that happen in the past, and it takes some massive amounts of fiddling with the CAS gear to get it lined up in a way to get the thing into it's adjustment range on the crank pulley.

Have you checked your car for any diagnostic codes?

il have a play with it on the weekend
havent got the scan tool on her yet
but hope to next week

il have a very good look a the timing
and let you guys know what i find

thanks for the help !

Let me know if you fix it, im having the same problem. I've tried 3 different maf's and nothing changed. I'm going to check the ecu for codes and the wiring tom.

did you come across any fault codes mate

cheers

[J240sx]

Yeah, i checked the ecu and got a code 12 for the maf. I switched it out for another one again but it didn't fix the problem. I checked all of the wiring before but I am going to go over it again this weekend to see if I missed anything. Hope I can fix it before it get's cold out.

[DRTY14]

check your timing mate mine looks
to be out ,should look like this[img][/img]
line the black links on your chain
with the dots on your cam gears
(turn the motor over until it lines
up, like the picture)

let me know how it goes .
cheers

Remember TDC is the second tick, not the first tick on the crank pulley.
