Rxroo87 Posted March 16, 2007 Share Posted March 16, 2007 first off its a 88 gl 5sp d/r 280k. the problem is that when you push the gas off idle it pops through the intake, it has no power the damn thing sounds like its making popcorn under the hood. checked the timing and compression they were both good. any suggestions would be greatly appreciated Link to comment Share on other sites More sharing options...
Phizinza Posted March 16, 2007 Share Posted March 16, 2007 I'm just speaking off the top of my head here but maybe the right side timing belt skipped a tooth? Did it happen all of a sudden? Or has it always been like that since you got it? Link to comment Share on other sites More sharing options...
Indrid cold Posted March 16, 2007 Share Posted March 16, 2007 could be something simple like cracked dist. cap, or loosed up, or rotor is slipping (loose screw) ... or plug wired burned through and grounding... *I have same year so interested in what you find.

misledxcracker Posted March 16, 2007 Share Posted March 16, 2007 +1 on the slipping rotor, check that screw! Link to comment Share on other sites More sharing options...
daeron Posted March 16, 2007 Share Posted March 16, 2007 It might also be a REALLY DIRTY MAF sensor, or something blocking the air passage going to the MAF within the housing.. Inspect the inside of the aluminum housing, at the top, to make sure that the small passageway that goes up to the actual sensor is not clogged in any way, and make sure both the skinny wires on the actual sensor are clean. Use brake cleaner, or carb cleaner, or Quick Drying electronics cleaner to clean the MAF, and be careful with those two filaments, they *are* somewhat fragile. Check the distributor stuff first, but this is another possibility. Link to comment Share on other sites More sharing options...

psylosyfer Posted March 18, 2007 Share Posted March 18, 2007 sounds like timing, or at worst a burned intake valve Link to comment Share on other sites More sharing options...
Rxroo87 Posted March 20, 2007 Author Share Posted March 20, 2007 87 gl fi pops through intake at idle i think it did overheat i stoped let the beast cool off and drove it about 1.5 miles back to my house shut it off ant went out later to start it and it started making that noise. the more i think about it wouldnt it have poor compression in that cyl if the valves are burned???? :confused: Link to comment Share on other sites More sharing options...

psylosyfer Posted March 26, 2007 Share Posted March 26, 2007 Just for the hell of it maybe make sure the distributer advance is not sticking, A long shot. but until it's solved, couldn't hurt to check. By popping do you mean backfiring through the intake, or some other type of popping? Timing Belt(s) will definately cause similar symptoms is either is off a couple teeth. Knew a guy who about went nut's when his Xt barely ran, backfired, no power , when it wasn't yet stalled again. (stalled every 3 or 4 minutes) He convinced himself that if put the belts on wrong it could not even start. So flat refused to consider rechecking ( I realize you did not just change belts but a few teeth slipped is the same as installng a few teeth off) He beat his head against a wall for about two weeks before getting passed his stubborn streak, Finally he found that the Pass. side cam turned a little without him noticing it when installing the belt. But I remember how it ran , sure sounds similar to yours. Link to comment Share on other sites More sharing options...
Sonicfrog Posted March 26, 2007 Share Posted March 26, 2007 Just a thought: would that model have a throttle position sensor? Link to comment Share on other sites More sharing options...

GeneralDisorder Posted December 19, 2007 Share Posted December 19, 2007 If a valve sticks in it's guide the rocker will just fall off. It can make quite a mess. I've seen it once. GD Link to comment Share on other sites More sharing options...

What else did you do to address valve problem? Did you replace that valve + guide? Or at least check the guide? What about the Camshaft? was there damage to that lobe? I hope it's ok for ya, but seems like it needed more valve issues addressed. That may be why it still running poorly. Link to comment Share on other sites More sharing options...
