On the day of my smog check as usual every other year, I burn through a tank of gas and an additive by the name of "guaranteed to pass" My ranger in years past doesn't travel far just a bunch of stop and start short trips and a mechanic told me years back that a lot of short trips would allow carbon to build up and this additive would help me clear out the pipes before testing and be able to pass or the company will pay you double what you paid for the additive if you do not pass, and I have always passed, not sure if it is or is not helping but the one time I didn't do it, it wouldn't pass! (Murphy's law?) Anyway, I burn through 1/2 or less of a tank on the day of the smog check so in the morning I started it up and before I got out of the driveway a "check engine" light lit up and went out and I let out a grouping of colorful metaphors! I went and hit the highway and got about 20 miles and on comes the light again! I pulled off the highway at a gas station and called off the smog check. Waited for a Bro to show as he was following me home, he showed, I started it up and hit the highway. No light until nearing my turn off (about 20 miles) light comes back on. After doing a KOEO test I got a code 332. Took the EGR valve off and cleaned it real good put it back on (had taken the battery cable (neg.) Off) fired it up let it warm up for a good 20-25 mins. Went back in it and the light was on. Checked for codes and didn't get #332 but did get# 335
The EGR valve might be original, and it was nasty it took a lot of elbow grease to clean, and the two mounting bolts felt like they were welded on! What I did notice was the intake manifold where the EGR valve bolted up looked like there was a valve. I haven't found anything about a valve in that area so now I'm thinking it might be clogged? My edgumacation LOL! As far as vehicles. Get ready to laugh! Is utube a good friend who is a retired mechanic (aka sees my hood up won't even look at me!) And to top it off with. A ranger Haynes manual. What I've been looking for that has yet to be found is a diagram of my EGR system as so I can disassemble and clean it so that I don't get any of this nasty stuff into the engine. I'm going over to O'Rielys to see if they have a vacuum pump and then I'm halting until I hear from you. I look forward to your response and I thank you in advance.
have the same problem?
