Hey, maybe someone of you have any ideas engine is a little bit backfiring, max rpm 3000 cant rev more, timing chain is in it position, tried a lot different crank and and cam sensors nothing helped, engine was fully working in other car before I bought it, all wires sensors everything is from my old engine. All 4 cylinders have spark but it seems not all are working together. When you start the car engine is a little shaking, always when I start the car the rpm goes to 2000 and after 10-15 seconds drops to 1000rpm and stays and when i try to rev the engine and it stucks at 3000rpm, also tried to unplug O2 sensor, MAF nothing helped.

Have you checked the order of your spark plug wires? Radiator side is plug #1 - 2 - 3 - firewall side is plug #4. The original wires should be labelled as well as on the coil pack cover. If you need an extra working coil pack message me :D -- Good luck !Last edited by othatseric; 09-07-2017, 01:17 PM.

Changed spark plugs to new ones, the car now can rev to the limitter, but still rough idle and then you get more then 2000rpm car makes lot of white smokes and strong petrol smell from exhaust, another thing I saw then i unplug MAF ant normal idle car goes from 1000rmp to 2000rpm is it normal?

So I changed all intake manifold gaskets (the old one was ripped like you said) to new ones I ordered. Checked again for vacuum leaks, also cleaned my ICV. Now everything changed. When I start a car it idles all the time from 800rpm to 1400rpm, when I try to rev it, engine stops. Also when i unplug MAF car engine stops.(a lot of gas smell) P.S changed temperature sensor. And also after i rev a car ant engine stops it is very hard to start it again, feels like it is to many petrol.Last edited by Hugas; 09-20-2017, 04:04 PM.
