Problem with my 98 Ranger

Hello everyone im new to this forum, i was in google looking for some information for my Ranger and I saw this forum and joined in to see if anyone could help me out with my issue. thanks in advance

I have a 1998 Ford Ranger XLT 4x4 its a 4.0 and I've been having an issue for a long time I've taken it to mechanics and even to the Ford Dealer Shop and they cant find the issue well long story short my Ranger keeps missfiring ive change plugs and wires, sensors even a injector and no positive signs. Last week I was told by an uncle that it could probably be the EGR valve, im not good in mechanic stuff so im not sure if it is. Im wondering if anyone else has the same issue or had it in the past.


p.s. im hoping im in the right sections if not, if someone could move it pls. thanks

Mine kept blowing #4 cyl. Literally I put z max in and it stopped ... It may be a bad o ring on an injector or it could go as far as a bad ring ... My advise if you have changed the coil and plugs and wires try z maxx

 

Thanks for the advice is there any special type I should ask for in Oreillys?

btw what I for got to metion was that it also has a fuel odor like if the gas wasnt buring right. but thanks ill try that z max and see what it does

 

I bet you have a emissions system leak then.. Check your connections to your carbon canister as well as your egr .. Egr might be bad as well

 

I might sound stupid but what's the carbon canister?

 

egr wont cause a misfire. And do you mean like a code was pulled that detected a misfire, or is the truck mis-firing and running poorly....?

Might be the crankshaft postion sensor. It tells the computer when to fire. If its firing early or late, it will cause bad missing/

Is there any popping thru the intake?

 

Yea it's misfiring and running poorly, and about the codes my check engine doesn't turn on

I bought that sensor too and it stop for a few days

 

try checking your cam and crank sensors for rust and also disconnect ur neg battery terminal and wait 20 min then put it back and go for a 2 hr drive, go on the highway n city streets, if tht dosent work then u may try replacing the coil pack

 

Thanks for the info I'll see what happens later

 

Yesterday I bought the zMax 2 of them one for the engine and the other for the fuel I hope it makes a difference..
