Lately i've noticed my car seems to have weak starting on occasion not first start up either, sometimes after driving for a while. Battery is fine and alternator is new, spark plugs and wires are fairly new also. And today i notice my car sometimes just didn't seem to have quite the power it usually does, and i'm also getting really bad gas mileage, probably if i let it run dry i could get 160 to a tank.maybe 170 Could this be my ignition coil? my friend's dad said that one of his trucks did that once but i figured i'd ask here. starting power is fine it just takes longer than normal (not always) doesn't sound like a weak battery though. The starter solenoid is new also. let me know what you guys think. Oh, about the gas mileage, i also changed the O2 sensor and the fuel filter/airfilter is new plus i changed the rubber grommets that go to my intake and pcv, and pcv valve and the filter that plugs into my intake and now there isn't any oil infesting my air filter.

Also will a leaky fuel injector cause bad gas....and how will i know if it is leaking? i looked at mine and the entire thing was wet even the top part...i wasn't sure if it was supposed to be or not.

BTW: it's an 84 SE 4cyl auto

A leaky injector could cause that but I believe you will get some gas in your oil if the injector is leaking. Anyone feel free to correct me if I'm wrong. I would check your wires coming from your battery, make sure they are clean and not corroded. If you have an ohmeter you can test your coil. does the check engine light come on while the car is running? if so pull codes. Good luck!

Oh yeah....the battery cable's are new also! About a week ago the check engine light came on once about 45 seconds after start up and it stayed on for about 10 and then shut off. I do not have one of those meter's. How would i know if gas is getting in my oil. I might be wrong but where my throttle body is on my car, the thing that is spraying gas into the engine, isn't that the fuel injector? how many do 4 cyls have. I don't know that area of my engine very well at all. But that gets soaked when it's running and whenever i shut if off say to check my air filter that is when i noticed it was wet. thanks!

A leaking injector will definatly cause poor gas milage but it will also cause poor idle qualities.

Things wrong with the engine that can cause bad milage are a stuck open or missing thermostat, Thermac (hot air door) stuck open, Clogged or saturated air filter, Radiator fan always on, Ignition timing.

You dont need a meter to get the codes.

If you want to check for codes, remove the ciggarette lighter plate in the center console. There is a connector to the passanger side of the center. put a paperclip in the A & B pins and turn the ignition ON but dont start the engine. The check engine light will begin to flash. Each code will flash 3 times then move to the next code.

Example of code 12
Flash pause Flash Flash long pause, Flash pause Flash Flash long pause, Flash pause Flash Flash long pause Next code will begin next.

I was under the impression that you had a v6. The L4's had one overhead injector. Start with the codes. Do a search on codes and you will find tons of pages.

We have a code scanner, i have not checked them but fan isn't coming on because i need a new fan switch because the one on my engine just broke off where it connects to the plug, air filter is fine/new...the thermac door thing is closed i guess it's supposed to be. Theremostat is fairly new. So do you think my fuel injector is leaky since it's always saturated in gas? Let me know! Thanks

To see if the injector is leaking just have someone turn the ignition on while you watch the injector. The fuelpump will run for 2 seconds just have them turn the key off and back on repeatedly.
