Bella: sick again

[mcmac]

Here are the codes that came up on Bella,she just sputters on take off but once she is warmed up everything seems fine....
she is a 98 and a month ago we had the same problems,changed fuel filter and she was happy now we have the same problems all over again. spark plugs and wires were done 2 months ago.Could it be bad fuel?


p1128 long term fuel trim B1 system too lean
p0300 random misfire detected
p0301 cylinder 1 misfire
p0302 cylinder 2 misfire
p0102 mas or volume air flow curcuit low input
p0303 cylinder 3 misfire detected

thanks goes out to anyone who can give me a few suggestions!

Could be, try the premium grade, that is what I use in my '98 despite the price and I have never had a sputtering problem during warm-up.

In a worse case scenario, there is always the Air Pump, EGR Sensor, vacuum leak, injectors or the coil...

could be a loose vacuum line.
Could be a vac line w/a hole.

Thanks for your suggestions,
would either explain why after running a month just fine
then crappy again? If I had gotten some bad fuel a month back could I still be dealing with complications and why would it run fine for a month then ****ty now?
its like something is clogged at start up then after a few pedal pumps and gentle speed she is up and running.
thanks

Intermittent problems are a pain in the arse to diagnose and aside from what has already been suggested, I just do not know...

However, if you truly think it is bad fuel there may be some sediment in the tank; if this is the case I would suggest that you drain and flush the fuel tank and/or replace the fuel pump.

Try to buy your gas at the same place. When I do my taveling I stick to the same places. A while back in Illinois on a couple of trips,I bought at different places,One place sold nothing but ethanol....I had no choice but to put it in.....I was on empty and no other places in site. I filled up and the car sputtered and coughed,After a few tries it started up and ran,This happened 2 times and I won't let it happen again. I stick with filling up at the 1/4 tank mark from now on. This gives me the option to shop around if they are selling the ethanol crap.
