Had the camaro (86 5.o v8 AUTO) out a few weeks ago for a bit rip,which it hadn't had for literally a year or so!! all was fine till heading home and the srvice eng light flickered, as it did the engine seemed 2 choke/lose power and it felt like it wanted 2 die, this was at about 10mph, then it cut out, started up 1st time and got me home which was less than a mile away thankfully, kind of kangarood all way home with light flashing intermittantly.
did a error code check following night after leaving it to sit and showed up no codes and ran fine the other 2 times i had it out, however i took it out yesterday and gave it one boot on the way home an it started it's crap again, i pulled over an turned it off for a few mins but was still same all way home, then when got in would'nt hold a rev, was a bit spluttery, would say a misfire but is kinda hard to tell? too me anyway, cuts out if not on the gas, ok ive now had it up 2 a tuning clinic and it went haywire on the diagnostics they think it cud be the ECM or a break in the wires to the ECM ive also been told it cud be vacume leak, MAF sensor Coolant temp sensor, oil pump!? i must add tho, its completely intermittant, always runs perfect cold then once it starts to heat the SES light will flicker then it revs its self then drops and runs lumpy then randomly revs again, altho on way home from tunic clinic trip aprrox 15 miles it ran terrible till i got onto bypass(high way over there ) and then ran perfect all way till i got to my street?? i so dont know where to begin, any suggestions wud be appreciated, thanx x

 

I had something very simliar happen to me when I had my 90 RS. When I fired the car up it was fine and after it warmed up, it would start to sputter and when you gave it gas, it acted like there was no power and it wanted to die.

To make a long story short, I made another phone call, but to a guy that was higly recommended and he said it's your spark plug wires.

Sure enough, I replaced them and it ran great once again.

Now I'm not saying that is your problem, but it's something to think about and plug wires aren't too costly.

 

hey thank you for ur reply..Hey just n update on this ***** of a car..did egr test ran same? put it in 4 MOT and garage cancelled half way thru due to it needing "so much welding" had it all welded up yesterday and wasnt tht bad at all so when i called garage to say i...ts been welded they pipe up "oh we forgot to tell u, its ur head gasket"!! So, had a friend out to replace thermostat and CTS ran perfect (for a while) not over heating what so ever and no water leaksm no oil in water vice a versa?? which makes me think not headgasket?? still to do a proper pressure test. so still have the 02 sensor and plugs to put on But now when starting it and heres the thing that hopefully someone can identify as prob 'light flashes almost like theres a break in the wire to the dash light say 2 slow flashes 3 fast 1 half a flash then just pure randomness basically and when it flashes theres a kinda clicking noise coming from very top of engine just where it says tpi on block, still not reading a proper flash code....is it my ECM
