Question about Ford Laser
Mazda soho 1.4i cvh fuel injection while iddling vehicle runs fine but when we give it gas to go vehicle looses power and i can only get 60km per hour max , checked compression it is fine , fuel is comming through to the injectors , timming is also fine and vehicle is getting spark on all 4 cylinders can you assist me please.
It could be that the coil is weak, or the igniter module is faulty (ie not giving the coil enough time to charge), or the fuel filter is blocked, or the exhaust is blocked. I have seen Cat Converters melt down internally and block up the exhaust pipe, causing faults like what you describe. Thats probably the first area i'd check, and easy enough to do so, just remove the Cat from the exhaust and take it for a drive. It'll be noisy, but if it goes heaps better then you know that is the problem. If it doesn't go any better, stick another fuel filter on it (it's probably due for one anyway) and see if that does anything. From there it's probably better to get a mechanic or auto electrician to diagnose the fault. It is also possible that the fuel pressure regulator could be faulty, not keeping sufficient fuel pressure in the fuel rail.
