So Ive been having trouble with my car sputtering and backfiring and I just cannot figure it out. I have a 1.7 FI. When i rev the car under load it seems like it just has no power. Cars been timed correctly, went through everything and I still cannot figure it out. Hoses look ok, exhaust bolts seem to tighten but wont tighten completly. Not sure if this would cause all these problems or not. Could my injectors be clogged or fuel pressure be to low? Can someone go through a test procedure for this? I really don't want to have to spend another 3 or 4 hundred dollars on this if its just something simple. Thanks Guys

Do you know if each plug is firing? What do your plugs look like. Are they black or look dry as a bone? Do they all look the same? With it running can you pull one plug at a time. Well not the plug but the wire to the plug. Pulling each wire in turn should help isolate a plug that may be causing trouble. You've probably allready done this but it's a simple thing to check (IMG:style_emoticons/default/smile.gif)
