95 ford ranger hard starting and high revving.

[lawnwizards]

i have a 95 ford ranger 2.9l 4 cylinder. tried to start it yesterday and it took about 5 seconds of turning over then it started. when it did start it revved really high for a few seconds then slowed back down. is this a problem or a one time thing? i really don't wanna have to put it in the shop. any help is appreciated. thanks.

actually my employee is the one who witnessed it. i tried starting it today without any problems. so to answer your question. no just the one time.

EGR-valve possibly sticking?

[TeeCee]

Vacuum lines off or leaking.

Throttle position sensor

well, i change the spark plugs and wires (8 of them) and it seems to run better. its only been one day but i'll post again tomorrow if its working better.

How exactly did a Ford Ranger have 8 spark plugs?

How exactly did a Ford Ranger have 8 spark plugs?dont ask me how. i just went to the auto parts store and they gave me the wires and 8 spark plugs. they were a bi*ch to install. very hidden.

Your employee started it with their foot on the gas.

Eight plugs....did you find holes for all of them or were there 2 left over. I look in ALLDATA at the shop and it has 2.9L as 6 cyl. Here is the data from AUTOZONE. If it only happened once then Notorious is right that he probably pumped the pedal or turned the ignition enough to hit the fuel pump before starting it. Did you gap them plugs...hope so.

we had a 92 or 93 ford ranger 4 cyl as well and yes it does have 8 wires and 8 plugs i didn't believe it myself when my mechanic was servicing it

i mistyped. its supposed to have said it was a 2.3L. sorry. i'll post a pic and show you guys.

[lawnwizards]

here ya go boys and girls. the pics as promised.:waving:

Its the same old Pinto Deluxe motor that Ford has had forever. Now its a fuel injected 4 cyl with 8 plugs and wires. An idle problem on start up with these engines would point to a slow IAC valve. If it was a one time thing, I wouldnt worry. Hard for a shop to find it anyway if it isnt happenimg when you bring it in. Yur just asking for a WALLET flush among all the other flushes they will say you need!

[TeeCee]

Ok 2.3L.....that makes more sense. Don't work on many Ford's....Mostly Hondas and Toyotas.

well..i still remain baffled on this one..i've never heard of an 8cylinder engine under 4.9liters..a 2.3 ford ranger is a 4CYL..unless somone did an engine swap..heck my '88 mustang is a 2.3l,yep and a 4banger!!..somethings a miss here

[TeeCee]

2 plugs per cylinder....Older Nissans used this as well

o.k. its doing it again but it only seems to do it when you've ran it awhile. then when you start it, it doesn't want to start and then when it does it acts as if its starved for gas. finally once it "gets gas" it then revs really high like someone is pushing the gas peddle down even though no one is. any ideas? thanks.

Are you sure its starving for gas and not flooding? I've seen several with leaking injectors that would flood the engine when hot. After the engine is shut off, they drip fuel into the cylinders. But... I would still go back and check the idle air control valve. Its the most likely culprit. Any check engine light?

yeah, the check engine light is on.

Ok... get a cheap, manual from yur local autp parts house. In there it will tell you how to pull the codes.( no scan tool required) Most parts places only will scan the newer OBD2 vehicles. You have what is known as EEC IV... EEC 4. Pretty easy to trouble shoot actually. Get those codes and get back to me.

[lawnwizards]

i just read where the 95 ranger is OBDII compliant. that means i can take it to Advance or Autozone and get the codes?

[lawnwizards]

got em.

p0118- engine coolant temperature circuit high input

p0125 insufficient coolant temperature for closed loop fuel control

p1443 evaporative emission control system contro valve. (i read somewhere that i need to change the canister purge solenoid/flow sensor assembly to fix this code)?

your help is greatly appreciated.

[xcopterdoc]

Yup..some 95's were OBD2 compliant. Thats a good thing.
Check your evap valve and see if is clicking. You should be able to feel or hear it clicking.
Next... check the wires to your coolant temp sending unit. You may have 2 sending units. One will be for the gauge and the other will be for the computer. disconnect wire, check for resistance from sender to ground. As the engine heats up the resistance should change and never go to a completely open or closed circuit.

[Dirty Water]

Also make sure your coolant is topped off and burped.The coolant temperature sender doesn't like air pockets, it messes with its reading.
