Btw, i reassemple the sparks, and try the car again, first 2 blocks run OK, but after that, start fail again. After that removed the MAF and the car dont work anymore. Reconnect it, and run again, but still fail. Removed the MAF again, and go worst.
When you say you "remove" the MAF, did you take it right out of the car?
To test the MAF you just disconnect it (pull the electrical plug out of the MAF) but the MAF should stay where it is.
Also if the car started to fail again after you took the coils out... then we're getting close to the problem. If the spark plugs are new then the coils and leads could be causing the problem.
Take the coils out (one at a time, so you don't get the HT leads mixed up..
) and take the lead out of the coil. Make sure the ends are clean and dry and in good condition. They're 14 or 15 years old now and they can become corroded or burnt.
Have a good look at the coil too, when you have it in your hands, to see if there's been any arcing. You might see little grey lines on it (like a pencil).
The inside of the coil's turrets (for the leads) should also be clean and dry and the connector on top of the coil should be in good condition too.
Did you notice the injectore light flashing when the car tries to accelerate?
