Community Links Members List. I'm new here and new to turning wrenches. I have an 86 F fuel injected. I'll start by listing what I have replaced, then tell you guys my issues.

Fuel Pump on rail and filter Fuel pressure regulator Idle air control valve Egr valve Egr valve position sensor Throttle position sensor Oxygen sensor Air charge temp sender Coolant temp sender Coolant temp sensor Starter and solenoid Vacuum lines from plenum to canister, fpr, evr solenoid, etc.

Plugs and wires gapped to. It almost never starts on the first try. After it finally idles down, it seems to idle fine. When I start driving, it seems good until about rpm then it feels like I hook to an extremely heavy trailer. Then from about rpm, it feels like it's missing. So, when I put a timing light on it after warming engine and removing spoutthe timing mark jumps around.

I can get it close to 10 BTDC, but I'm not sure with the jumping around. I'm clearly not a mechanic and I understand that I have thrown a lot out there with this one, but any suggestions on where to look would be great. First, welcome to the forum. You have done a pretty decent amount of work but I need to start with the basics. Have you Verified the firing order and have the wires connected accordingly? Also, have you checked the condition of the cap and rotor and also made sure that the distributor is in the right spot gear wise?

The person who 2005 ford f150 fx4 msrp it before me said that the distributor, rotor, forex spread low platform mini trading, and nigeria forex forum posting is all new.

I'm not sure what the condensor is, but I have pulled the cap and rotor.

It all seems to look pretty good in there. I have absolutely no idea how to check the distributor gear wise. On a different note, I read in the Haynes that the wires on the TPS should be facing forex currency trading seminars brisbane from the idle air control valve. A few weeks ago, I took the old one off and put the new one on and the wires were facing the IAC.

Today, I took the throttle body off and replaced the new TPS with the wires facing the EGR valve. Here's the funny part No difference at all. Again thanks for all of the help. Shouldn't be the same with wires reversed. The wiring is all shared by the MAP, EGR position and the coolant temp sensor so everything might stop working if it were backwards.

Without having the TPS in front of me to see the pin numbers it would stock market abbreviation for silver hard to tell what is correct.

Sounds like I've got some pretty serious issues that are far beyond my skill level, huh? Do you know where the engine control computer is on this particular model? I'm starting to wonder if something might be burned in there. Again, thanks for the replies. Normally the ECM is located behind the passenger kick panel.

While you're in there, check all of the splice joints to make sure they're still connected. Today, I tested the MAP sensor VREG is at 5. I broke my mityvac so I had to cheat.

Anyway, long story short, I market capitalization of major stock exchanges the MAP sensor back in and rechecked my TPS. I then reset my timing, as best I could with the jumping, and the darn truck runs great now.

The "trailer pulling" sensation is gone and the "missing" is much less noticeable. The only problem now, is it idles at about RPM. I'm kind of scared to back the screw out on the throttle body. Should I just leave it like it is? I would experiment with the idle speed a bit. Who knows, you may just find that sweet spot it wants. Glad she's running better!

Ok, so I played with the idle speed and as I pulled out of the driveway, it stumbled once and then idled fine. It may be a little low, but I'll keep working at it. At this point I guess the only things I need to address is the slight miss and my four-way flashers.

Speaking of my four-ways Is the "relay" the same one as the turn signal. When I turn the four-ways on, the just stay stuck on. I can't thank you enough for all of your help. There is a separate hazard flasher and, you're welcome!
