fuel, spark or air? help please!
Having issues on my 96 disco. *Wondering if yall can give me some help? Truck runs*smooth*at idle and when given some throttle, runs smooth through first gear and as soon as i shift into second, it bogs down. At first I thought*coilpack, so I replaced the entire $400 rail. I had a new alternator so I put that on and I'm still having the same issue. Truck sounds/acts like its not getting enough fuel or spark. Fuel pump or filter?*high side relay for fuel pump? Mechanic*tested the MAF and said it was all over the place, maybe its that? Whrn running, if I unplug the MAF, the motor bogs down for a second then goes back to normal. Any help would be awesome! !__________________

Stop throwing so many parts at it.
Buy a can of CRC made-for-MAF sensors, and spray it when the engine is cold and you have not turned the key for over six hours. A small spot inside heats to 350F, and does not like cold shock.
Fuel pressure test point on rail should read 32-34 psi. Fuel filter under right rear wheel arch. Changed in memory? Ever?
Fuel pressure regulator on driver side back corner of rail - six inch vac hose, any splits?
Plug wires ever changed? Plugs?

MAF cleaner worked for me, as well as replacing plugs and wires Also, throw a new air filter at it

Trucks new to me, so I'm not sure about what's been changed. Luckiky the P/O thought it was the coilpacks and gave me the whole rail of new ones! $400 I didn't have to spend and tbe new alternator was free also. I sprayed the MAF with cleaner, it ran slightly better but still same issues. Also I can hear the relay for the fuel pump when I turn the truck on, but I dont hear it switch back off. Is there a low end and high end fuse?
