Stats - 302 with Mass Air 91 Grand Marquis CA EFI recently installed. Has been running perfect up until this time. C4 tranny.
So on the way home from SOB when I gave the EB some throttle it felt like it was having a hard time, kinda of like there was a bind in the transmission. If I was at crusing speed the front end would dip slightly as it tried to give power. The tranny was not over heating and it was not pulling to either side so I figured it was not a brake or hub binding.
I stopped a few times to try and check it out. The problem got worse but seemed to start being more of an engine problem. Would take off I had no power to get to crusing speed and egine was popping from what sounded like the header area. Once I finally got to crusing speed every thing seemed fine unless I stepped on the gas or started up a hill. As I got into the hills to go over the pass it got worse then finally trying to go over the pass I had to pull over. I was going 10 mph up hill at full throttle.
Once I pulled over the fuel pump shot off and would not go back on. So it wouldn't restart. After about 30 mins the fuel pump decided to start working again (the problem must have been the computer turning it off because I checked it with a meter and it wasn't getting a signal.)
One I got it started, with a lot of effort, I tried to get back on the highway but couldn't get up enough speed going up hill to make it on to the road safely and the engine was running terrible and popping from the header area again (not back firing)
So I got a tow up the hill from Tom Drummer aka Pigpen which is an etirley different story about crapping my pants.
Once I got over the hill I used the down hill to get up to speed and it ran ok down hill and at speed to get me to Tom's Dad's house. he lives up a mile long pretty steep dirt road. I made it up but the engine was popping often and every time it popped I got a one second surge of power. I finally made it up the hill at full throttle only going about 5 mph. Trailered it home from their.
Currently the fuel pump comes on but it is very hard to start but eventually will start and idle perfect. Hesitates if you give it gas but will get the RPM's up.
So here is what I have checked. Timing is spot on. Pulled code with engine off - passed Pulled codes with engine on - 33- EGR valve not opening properly. (I used the resisitors from Ryan to eliminate the EGR and never got this code before.) Coded - 44 - Termactor Air System fault
Also ran the cylinder test and shows cylinder 7 not fuctioning full.
Any body have any ideas where to start?
Sorry for the long post and thanks for the help.
