hey everyone im looking at gettin another 2nd gen this is a 97 single cab 4x4 long bed slt package with a grill guard and a roll bar with a lift and aftermarket wheels and tires and a 700 watt sub behind the seat it has 131,XXX miles and has the 360 in it with a rebuilt tranny with wryt still on it now the badish lol would a tune up fix the number 5 cylinder miss fire when under heavy throttle?? all feedback is greatly appreciated thanks guys always know i can count on ya'll

 

wow only 16 views and no replies wheres the love ppl and he only wants 3500 obo for it ...... i was wondering what yall think the cause of the misfire is

 

The misfire could be a bad injector, a bad wire, a bridged plug, improper gap, bad cap, burned valve ... any number of things. We, as you, would need more information and some troubleshooting to determine the cause.

 

I've been plagued with the infamous cyl 5 misfire many times. 1 make sure the #5 spk plg wire is away from the #7. Then as TMS said chk fuel injector etc. Also take off the valve cover and check the valve spring on the #5 to make sure it isn't broken and while you're at it check the rockers to make sure there's no play. Make sure the plenum gasket is ok by looking doen into the TB, if you see oil residue down there then replace it. This is just a starting point. If it persist let me know and I'll continue.

 

ok thanks i talked to the guy more and he said the truck uses oil but not to bad so i think its the plenum gasket and if i do replace it i want that kit from hughes for 86 bucks lol so do yall think 3500 is ok for this truck?

 

i would do a compression check. if number 5 has low compression, then you have a head or valve problem and it will need a $1500+ repair, and in that case, i wouldn't pay that much for it. if compression test is ok, then it might be plenum or injector or plug or wire and it might be only a $500 repair. if that's true then i'd look up 97 KBB private party value (NOT RETAIL) and pay no more than that.

if you get the hughes kit get the the whole kit w/ new bolts for about $150. the old bolts are not designed to be re-used.

 

I agree with dh it's not such a bargain when you have to spend the money you're saving to repair the rig just to be able to drive it around. Might as well save your money and find one that has been taken cared of. Your decision of course.

 

well the truck drives good its just under heavy heavy throttle when the check engine light came on and the code was #5 misfire
