HELP surging engine

[adrnln]

Ok guys I think i am in the right area.

My 89 Ceffy has been great, BUT recently only in the mornings when taking off it feels as though someone is pulling the handbrake on at about 2000 to 3000rpm but as I drive through it it goes away, and then starts over again in the next gear so on and so forth till the engine warms up about 15mins or so later.

pls help with this issue as it is giving me the shits as well as the G/F

As far as I think its just the engine warming up. 15mins is a fair while tho... Mines now with the colder weather about 5-6mins.

chek the fuel pressure it may be low due to bad earth in the fuel pump had the same problem in my 180.

[jaik]

Mine does the same... its as if it retards the timing then all of a sudden goes back to normal and gives you a nice swift kick in the pants! Again, only happens when the motor is cold. Doesnt retarding the timing increase cylinder temps therefore warming the motor up quicker... might make sense?

yea my does that ....pretty much since i bought it ...i thought it was just normal with turbo cars?....cause i know a few other people who also experience it with a turbo u12 bluebirds

[BenA31]

yeah most cars do it when cold. just don't try giving it alot of throttle till its warmed up. if its taking so long to warm up (15min) then i'd check ur temp sensor or even thermostat

[adrnln]

Cheers guys your inputs been great, I have never really had this problem at all just only recently but I do live in Darwin and the wet season isn't the coldest time of the year. So I could possibly think that the weather could be a factor in this

[Ceffy_SA]

Yea mine does the same thing for about 5-10 mins (depending on weather), i think its just the engine retarding the timing to create more heat and warm the engine up faster, you would probalby find that if your cefiro is turbo the turbo starts spooling up earlier and with alot less throttle.

Does anyone know what sensor triggers this, is it oil pressure/temp or water temp or both?

[jaik]

Oil pressure is negligable but water temp is a contributing factor.

mine's been doing them for the last couple of months... funny how my gtst and gtr never did that even when the motors were cold... :confused:

[dangerous_daveo]

Bloody Darwin??? Does the thing ever actually COOL down??? If your up there Id say 15mins would be excessive.

i know this could be way off and slightly off topic, but would the fact that most of us are probally running the original auto computers (assuming with the limited amount of genuine manual ceffy's that were made) with now manual change anything with the timing when starting/warming up? (eg are the ignition maps different?)

anyway dude as i have mentioned and as jaik also touched on, check ur thermostat (could be siezed open) and coolant temp sensor (could be old and faulty/corroded).

other then that might be best to post ur issue up in the tech area as alot of r32 drivers would prob have experience/knowledge with such an issue aswel.

coolant temp sensor (could be old and faulty/corroded).

i changed the coolant temp sensor on my ceffy and it made no difference.

[adrnln]

cheers guys will check all these and post the results

mine is a stock manual and it surges when cold for the first 5 to 10 minutes or until the temp needle reaches the middled of the temp guage ..then it stops ...so i dont think its that

[BenA31]

^ fair enough, thought i was off, but worth a try asking.

cheers for clearing that up

[cefiro]

I have had a 32gtst, tt300 and the cefiro and they all have done it, if you find out what it is then your up for a noble prise in my opinion. I think its the timing being retarded, or a faulty sensor as latley I havent had it everytime I have started the car when its cold. I did go for a thrash and that seems to help it for a little while. The other thing my car gets is a slight splutter at cold idle as well, so the retarding seems to be right.

hope someone fixes this dilema

[adrnln]

Will be sending the car in for a service soon and a check of things so hopfully I can work out the problem. (fingers crossed)

Darwin can get COLD 17 degs (ok I'm used to 31 daily) forgive me I live here.
