System running lean, almost 300000 miles.
Started today, ran in failure mode, beginning to consider new injectors. New O2
sensors, New MAF, actually idles better with the MAF disconnected, also low voltage at
MAF, but it tested fine previously. Planning new IAC, and a distributor. 351 Windsor.
Check air filter and clean the (MAF) with mass air flow sensor spray.
The MAF may need replacing if cleaning doesn't solve it. Is the check engine light on? Why are you throwing parts at it? Determine the problem and repair it.
O2 sensors, and MAF are new, just ordered IAC and distributor, ran (ok) just a few days ago, I drove it with two plugs missing for too long, replaced ICM, and coil, New stator on the distributor but still coding 300000 miles and I want to get 500000 miles out of it. I use the Econoline to tow my Toyhauler, and with the 351w it's a little under powered. I know I'm throwing parts at it but I am hoping to have an interlude of no problem.
