l67ss Posted March 19, 2014 Report Posted March 19, 2014 L67 swapped my car and it ran like a beast...for a few days. Now it cuts out and spits and sputters under wot. Tried another icm(which fixed stuttering tach), swapped coils, tried another set of plugs, new plug wires. No real change. Also 8/10 of the time ir fires rite off, 2/10 time i have to crank the hell outta it. Fpr is a 96 . Fuel pump never gave any issues previously. Thanks Quote
94 olds vert Posted March 19, 2014 Report Posted March 19, 2014 (edited) I would say that is right were it should be. I have 42psi at idle. How's your MAF? I had a issue very similar to that, and my MAF never turned on a SES light. Wasn't until I data logged it I figured the MAF was bad. Edited March 19, 2014 by 94 olds vert Quote
l67ss Posted March 19, 2014 Author Report Posted March 19, 2014 Also forgot to mention i have some bs cobbled exhaust. Gonna weld up some good pipe, just havent had a chance. Quote
l67ss Posted March 19, 2014 Author Report Posted March 19, 2014 Actually just tried unplugging the maf, made it run really rough I would say that is right were it should be. I have 42psi at idle.

nitehawkjcb Posted March 19, 2014 Report Posted March 19, 2014 Check the PCM for codes, if you haven't already. Make sure your plugs are gapped correctly. I've had similar issues with a MAF issue and with a TPS issue. Quote
l67ss Posted March 19, 2014 Author Report Posted March 19, 2014 Turns out the maf was broke, how does that happen? Anyway, would it b a good idea to try my spare tps? I scanned it, no new codes Quote
94 olds vert Posted March 19, 2014 Report Posted March 19, 2014 Im good! Lol When my MAF up and died I went put in a new TPS. No code, but when I scanned it it wasnt working perfectly. With a new one its perfect. Quote
l67ss Posted March 19, 2014 Author Report Posted March 19, 2014 Yeah i wouldnt hav pulled it out if you hadnt posted. Ill have to grab abother maf at the jy tomoro, my spare is cracked too lol Im good! Lol When my MAF up and died I went put in a new TPS. No code, but when I scanned it it wasnt working perfectly. With a new one its perfect. Quote
l67ss Posted March 20, 2014 Author Report Posted March 20, 2014 Almost forgot, a code popped up for a tcs solenoid Quote
nitehawkjcb Posted March 20, 2014 Report Posted March 20, 2014 Ugh. The TCS code could be caused by a failing TPS - but most of the time you end up needing to pull the transmission and replace it. Might as well do the PCS and other shift solenoids while you're in there. I'm not sure how the MAF gets cracked, but I've seen it before. This is why I have 2 MAF sensors on hand at all times lol Quote
l67ss Posted March 20, 2014 Author Report Posted March 20, 2014 Yeah i dont trust this tranny. I found a 70k mile one from an 01 gtp though for $125 Ugh.

94 olds vert Posted March 20, 2014 Report Posted March 20, 2014 That a good deal especially with only 70k miles. Quote
l67ss Posted March 20, 2014 Author Report Posted March 20, 2014 The guy had bought a 99 and 01 gtp parts cars for his 00 gtp. Sold the 00 gtp and most of the parts and got into neons lol. He just has a few random gtp parts left, the tranny is one of them Quote
94 olds vert Posted March 20, 2014 Report Posted March 20, 2014 Neons are dumb. I wouldnt touch it witha 10 foot pole. Quote
l67ss Posted March 20, 2014 Author Report Posted March 20, 2014 Ive made a bit o $ workin on other peops neons Neons are dumb. I wouldnt touch it witha 10 foot pole. Quote
l67ss Posted March 21, 2014 Author Report Posted March 21, 2014 Just had a thought....could a REALLY bad sc coupler causw the same issues? Noticed it really doesnt whine much anymore Quote
Imp558 Posted March 21, 2014 Report Posted March 21, 2014 I'm not sure how the MAF gets cracked, but I've seen it before. This is why I have 2 MAF sensors on hand at all times lol How Wierd, I had a cracked MAF too! Actually since you're having these things in tandem it reminded me of an oldschool mechanic when mine was first shifting funny, he told me a bad MAF can screw with the tranny. I don't know how, don't kill the messenger but it improved when I got my new MAF, I mean NEW though. Quote
nitehawkjcb Posted March 21, 2014 Report Posted March 21, 2014 A bad coupler would sound like you have rocks in the blower. Make sure you don't have vacuum leaks or exhaust leaks, they can drown out the whine. Quote
l67ss Posted March 21, 2014 Author Report Posted March 21, 2014 Changed coupler and maf, car has balls again . Still a lil stumble under wot but no ones dicking and covering thinkin its a drive by . Also shortened the life of my front tires a bit Quote
Imp558 Posted March 21, 2014 Report Posted March 21, 2014 Did you save the old SC oil to pour into people's cowls when the double park? It has an aroma all it's own Quote
l67ss Posted March 21, 2014 Author Report Posted March 21, 2014 Thought about using it to slick back my hair Did you save the old SC oil to pour into people's cowls when the double park? It has an aroma all it's own Quote
l67ss Posted March 26, 2014 Author Report Posted March 26, 2014 Well it started f@#$in up again so i did another fp test. 43 psi@ idle, 50 psi @ 4000 rpm, so the pumps good. Went to walmart and bought carb cleaner. Sprayed it around injectors while idling, idle slightly fluctuated. Sprayed a bunch on each so it puddled revved it up and it sucked it down. Gonna o ring my spare injector and try those Quote
