Allo,

My E30 start jerking when i try to accelerate and after shift gear..enjin macam nak mati tapi tak.. cuma macam semput-semput..sekejap ada pickup sekejap tak ada..RPM langsung x boleh cecah 3K..drop gear pun sama juga..

So sifus out there please help, what is possible problem? Cannot stand anymore just can speed last 90 kmh only..kancil potong senyum saja

jerking?

Ikut sequence, yang penting rotor arm.

1. Check rotor arm (tukar baru atau get a good 2nd hand)
2. Plugs cable and spark plugs (check, kalau kotor tukar all 6)
3. Plugs cable leaking current.
4. Check fuel filter
5. Check fuel Pump

could be a vacuum leak or ur AFM needs some cleaning .
just a guess

Thanks bro highwaystar and wks79.

Actually the problem happened after i service the car (changed spark plugs, engine oil and oil filter). Maybe my plug cable 'koyak' or as bro highway said rotor arm worn out. Will fixed it as soon as possible.

just curious whether the check engine light on? u said u just serviced the car so guess worth checking the O2 sensor, who knows the mechanix might accidentally unplugged it while pulling the jack:) just a thought though:)

anyways u might wanna check these in sequence kekekke...
1. fuel filter
2. plugs
3. cables
4. fuel pump
5. vacuum hose
6. afm

you can always test the O2 sensor by unplugging it and take a drive. If there's a difference, change the thing.

my 2 cents

O2 sensor on Jetronic? got meh? so far that i know only motronic.

hehe bro jeembo, my car got no 02 sensor la..no check engine light warning but sometimes when revving the engine like no power, press pedal to the floor but engine seem want to die..will send to workshop in this weekend..Will update soon.

anyway thanks for your advice.

tak..tak kuar asap apa pun..

check the air flow meter. get it calibrated properly.

how to calibrate ah???oso where can check for TPS faulty or not?

if im not mistaken, they use the o2 machine to test it and the TPS can be adjusted below the throttle body.

Sent the car to my mech...he just changed fuel filter and wallaaaa my car can rev again Thanks all for the advice..
