Engine Troubles [Solved]

pull a spark make sure they are ok, should be an iridium

$60 denso sk20hr11 ---- IRIDIUM PLATINUM power pack spark plugs -- # 3421 ----- 6 PCS NEW

denso sk20hr11, if its not DENSO or NGK plug might be the problem

 

Does the engine have Variable Valve Timing?

 

They are Boach Double Iridium.... should I replace?

 

Not sure this has anything to do with anything... when I start the car and it is running the Tach dose not register anything it dose not move at all.

 

that's the problem pull them BOSCHES out and put in a DENSO or NGK iridium tip, the DENSO is

SK20HR11, or look in the owners manual for the required plug model and get them

 

Check all the fuses under the dash. Pretty sure one of the little 5 amp guys powers up the data link connector

 

he used those BOSCH spark plugs that's why its not running he needs to put in the proper DENSO or NGK plugs and its fixed

Apr 21, 2014 - I have a 97 Tacoma 2.7L. When driving at highway speeds for no reason the truck sometimes cuts out or feels like a miss. .... I use Royal Purple 5w-30 synthetic motor oil and Bosch Platinum 4 prong spark plugs. .... Toyota tacoma 2002, truck sometimes won't start unless

 

when did the bosch plugs go in?
If it was running before with the bosch plugs then thats not the problem

 

Maybe ask the friend you got it from about if or what was added or deleted?
What happened what was he/she doing when it died.
Was it running when you got it?
Your reader doesn’t connect, the tach doesn’t do anything, is that all the electrical gremlins.
No mechanic here either just gotta think maybe it’s electrical.
Did it go for a swim or something like that?

 

no way first thing is put in the proper DENSO or NGK plugs and get those Boschs out that's definetly whats going on with the engine, they run like shit in Toyotas and cause all kinds of problems

New info. The car was running before the previous owner replaced the water bypass pipe... then it was not running after that.

 

Even cause the Tach not to work?
I will agree, he should use the correct plugs.
But I’m not seeing how incorrect plugs would cause a data link or tach issue?

 

im not quite getting this whole nightmare, the data link in the truck must be broken cause he has tried 2 OBD scanners neither linked up?? if he can get a code up the mystery is over, my money is on the BOSCH plugs being the issue

 

Check those fuses i mentioned

 

Pulled all the fuses under the dash. The OBD2 scanner is powering on. It will not link with the car. Says Linking Error

 

All the fuses out under the hood okay? Anybody jump the car backwards at the battery? Check all the connections that may have been unplugged recently, look for damaged pins.

It could still be the maf sensor. Really need to get the data link connector working not just for codes but to look at data also. Otherwise you're just throwing parts at it

 

I'm thinking either water damage or he tried to tune the ecm and locked it up.

 

Well the goal tomorrow is to take the intake manifold off to see if the previous repair (water bypass pipe replacement) was done and there is just a missing connection.
