Ok so I know this isnt exactly the cheapest way to be going about this but with my '86 trans am TPI 5.0 Auto transmission ive been getting an ses light for code 36, Burn off at mass air flow sensor OR Problem in transmission shift OR Fault in direct ignition system OR Missing pulses in electronic spark timing signal, I just finished rewiring the connector for the MAF sensor burnoff relay, replaced the MAF sensor burnoff relay, replaced the MAF and yet im STILL getting this code 36, i just had the transmission rebuilt, so im not so sure its that... the only thing i can think of is possibly i wired the connector wrong? the code only sometimes comes up but it always comes up within 5-10 seconds of the engine running... does anyone have any suggestions? anything would be greatly appreciated! Btw I have a hypertech thermomaster chip.. dunno if that changes anything or not..

 

gm has a tsb on this issue! check on no data (alldata)

 

I'm also getting a code, 33, 34, and 36 I've checked all the terminals and connections and grounds are clean. And since I'm going to school to become a automotive technician, I used the diagnoses process from ALL DATA for code 33, and I'm doing code 34 tomorrow after work, and after the test for code 33, it says it may be a faulty MAF, but until I took the car apart, it was fine, and the MAF sat in my basement for 5 years, until last weekend, so I don't think its the maf. I'm also going to finish the diagnoses work for code 36. So if I may ask, What do you think it might be?

The Maf burn off relay's working, because after I shut the car off, the burn off relay, burns up the MAF wire, so its working. I don't think having 1.6 roller rockers or advanced cam should be affecting it though.

 

Well heres the deal, this is funny, it was actually nothing wrong, lol.

I first did the normal method of clearing codes on any OBD I GM vehicle. Pull the ECM fuse out for 10 seconds, put it back in, and your good to go. So I did that like 4 or 5 times, put the fuse back in, and checked the codes, and still codes 33, 34 and 35.

Then I pulled the fuse out as All Data said for 5 minutes, tried that a few times; still same thing, 33, 34, 35 codes.

Then I went ahead and did the older, slightly more pain in the *** method, but no big deal, pulled the negative battery cable for about 12 seconds, put it back on, checked the codes, GONE! Then ran the motor, a few times checked codes again, and GONE!

I mean before I was setting up my New CAI I need since the new radiator is bigger than the stock, plastic core junkers, that break. My 87 irocs and my formula both broke the same way, so after the have 125K on them, the plastic turns to shi* and cracks. So I bought a summit universal fit one, and its larger than the factory one, which is good anyway, because this motors making more power now, and I'm fabbing up my upper radiator hold down, and the two attaching points for the fans to bolt to. So anyway, I'm just finishing that up, and have the first half of my CAI done, I just have to cut one more piece of 3" tubing, I'll cut in my machine class, because the band saw does a much nicer cut than a hack saw and straighter than a saw zahl. So I'll post pics of that in a few days.
