is it true that the only way to set the timing is by computor i have a 1.4spi 1996. my timing has been checked by timing gun but a garage told me today that it has been done wrong and the only way to time it up is by computor it basically adjusts the ecu setting for timing.if this is the case why has it changed so it runs ****e i have had a new throttle switch/temp sensor/map sensor all new not secondhand.but it is gutless
You can use a timing gun but i think garages just put an exhuast emissions sensor onto the exhaust, this tells them whether its running rich,lean etc. And displays whether its firing on all fours etc
Which can then lead to the timing, they then alter the timing to get it running just right.
Take it to a rolling road.
